Parashah & Haftarah Study

Parashat Va’etchanan & Shabbat Nachamu

The Ten Commandments, Moses the Teacher, and the Limits of Interpretation

Parashat Va’etchanan contains several of the most foundational passages in the Torah: Moses’ plea to enter the Land, the renewed presentation of the Ten Commandments, the Shema, the prohibition against adding to or subtracting from the commandments, and the preparation of a new generation for covenantal life in the Land of Israel.

Before the class, students were invited to choose among several possible topics: the differences between the two versions of the Ten Commandments, the Shema, the principle of Bal Tosif—“Do not add”—and the Haftarah’s opening proclamation, “Comfort, comfort My people.” The two leading choices were the Ten Commandments and Bal Tosif, and these became the central focus of the lesson.

We studied Moses not only as a prophet and lawgiver, but as Israel’s teacher. Standing at the end of his life, Moses must transmit an ancient revelation to a generation that did not personally experience all the events of the Exodus and Sinai. He retells, interprets, explains, and applies the Torah—while simultaneously warning Israel not to add to it or subtract from it.

The lesson also took place between Tisha B’Av and Tu B’Av. We compared this transition to the relationship between Israel’s Memorial Day and Independence Day: grief is not erased, but becomes part of the responsibility to rebuild, renew, and continue. Shabbat Nachamu begins the movement from destruction toward consolation and restoration.

This class explores Moses as teacher and mediator, the trust required between teacher and student, the covenant with the generation entering the Land, the two versions of the Ten Commandments, the different meanings of the Sabbath, the wording of “You shall not covet,” and the tension between preserving revelation and building interpretive traditions around it.

Parashat Va’etchanan

From Tisha B’Av to Consolation and Renewal

We began with an overview of Parashat Va’etchanan and the major subjects found within it: Moses’ plea to enter the Land, the renewed presentation of the Ten Commandments, the Shema, the warning against adding to or subtracting from the Torah, and the Haftarah’s opening proclamation, “Comfort, comfort My people.”

Before the class, students voted on the topics they most wanted to study. The options included the differences between the two versions of the Ten Commandments, the Shema, Bal Tosif—“Do not add”, and the Haftarah of Shabbat Nachamu.

The two leading choices were the Ten Commandments and Bal Tosif. We therefore built the main part of the lesson around these two subjects: how the commandments are repeated and interpreted in Deuteronomy, and how Moses can explain the Torah while simultaneously warning Israel not to change it.

We also discussed the relationship between Tisha B’Av and Tu B’Av. We compared this transition to the relationship between Israel’s Memorial Day and Independence Day. In both cases, a day of grief is followed by a day associated with life, continuity, and rebuilding.

The movement toward consolation begins immediately after Tisha B’Av with Shabbat Nachamu. The Haftarah opens a new liturgical season in which destruction is not forgotten, but the emphasis moves toward comfort, restoration, and renewed hope.

Central idea: Parashat Va’etchanan stands between memory and renewal. Moses looks back at Sinai and the wilderness, but his purpose is to prepare a new generation to live, learn, and preserve the covenant in the Land.

“And Now, O Israel”

Moses the Teacher and the Trust Behind Every Tradition

Deuteronomy 4:1

וְעַתָּ֣ה יִשְׂרָאֵ֗ל שְׁמַ֤ע אֶל־הַחֻקִּים֙
וְאֶל־הַמִּשְׁפָּטִ֔ים אֲשֶׁ֧ר אָנֹכִ֛י
מְלַמֵּ֥ד אֶתְכֶ֖ם לַעֲשׂ֑וֹת
לְמַ֣עַן תִּֽחְי֗וּ וּבָאתֶם֙ וִֽירִשְׁתֶּ֣ם אֶת־הָאָ֔רֶץ אֲשֶׁ֧ר יְהֹוָ֛ה אֱלֹהֵ֥י אֲבֹתֵיכֶ֖ם נֹתֵ֥ן לָכֶֽם׃

“And now, O Israel, listen to the laws and the rules that I am teaching you to observe, so that you may live and enter and possess the land that the LORD, the God of your ancestors, is giving you.”

The opening expression וְעַתָּה—“and now” marks an important transition. Moses has reviewed the historical background: he will not enter the Land, Joshua has been appointed to lead the people, and the new generation is preparing to cross the Jordan.

Moses now moves from history to practice—from what happened in the past to what Israel must do next. The words “and now” introduce the practical implementation of the lesson.

We noted several expressions that are characteristic of Deuteronomy:

הַחֻקִּים וְהַמִּשְׁפָּטִים — “the laws and the rules”
מְלַמֵּד אֶתְכֶם — “I am teaching you”
לַעֲשׂוֹת — “to do”
וִירִשְׁתֶּם אֶת־הָאָרֶץ — “you shall possess the Land”

Moses is presented not only as a prophet or lawgiver, but specifically as a teacher. His teaching is not directed toward knowledge alone. The participle מְלַמֵּד—“teaching” is completed by the infinitive לַעֲשׂוֹת—“to do.”

Moses teaches so that Israel will act. Biblical teaching is therefore directed toward practice, life, and responsibility in the Land.

We then discussed the role of tradition and mediation. A written text does not read, pronounce, or interpret itself. Every student receives the text through teachers, language, pronunciation, and previously transmitted knowledge.

This idea was illustrated through the story of the convert who came before Hillel and said:

תּוֹרָה שֶׁבִּכְתָב אֲנִי מַאֲמִינְךָ,
וְשֶׁבְּעַל פֶּה אֵינִי מַאֲמִינְךָ.

“Regarding the Written Torah, I believe you; regarding the Oral Torah, I do not believe you.”

Hillel taught him the Hebrew alphabet in its familiar order. The following day, he reversed the order of the letters. When the student objected, Hillel showed him that even the identification and pronunciation of written letters depend on trust in the teacher.

The story does not claim that a teacher can say anything. It teaches that no written tradition can be transmitted without a relationship of trust between those who preserve it and those who receive it.

Central idea: Moses is not merely repeating commandments. He is teaching a new generation how to live by them. Every act of teaching requires interpretation and trust—but that trust also gives the teacher a responsibility to transmit the text faithfully.

The Covenant Was Made With Us

The Introduction to the Ten Commandments and Moses as Mediator

Deuteronomy 5:1–3

וַיִּקְרָ֣א מֹשֶׁה֮ אֶל־כׇּל־יִשְׂרָאֵל֒ וַיֹּ֣אמֶר אֲלֵהֶ֗ם
שְׁמַ֤ע יִשְׂרָאֵל֙ אֶת־הַחֻקִּ֣ים וְאֶת־הַמִּשְׁפָּטִ֔ים
אֲשֶׁ֧ר אָנֹכִ֛י דֹּבֵ֥ר בְּאׇזְנֵיכֶ֖ם הַיּ֑וֹם
וּלְמַדְתֶּ֣ם אֹתָ֔ם וּשְׁמַרְתֶּ֖ם לַעֲשֹׂתָֽם׃

יְהֹוָ֣ה אֱלֹהֵ֗ינוּ כָּרַ֥ת עִמָּ֛נוּ בְּרִ֖ית בְּחֹרֵֽב׃
לֹ֣א אֶת־אֲבֹתֵ֔ינוּ כָּרַ֥ת יְהֹוָ֖ה אֶת־הַבְּרִ֣ית הַזֹּ֑את
כִּ֣י אִתָּ֗נוּ אֲנַ֨חְנוּ אֵ֥לֶּה פֹ֛ה
הַיּ֖וֹם כֻּלָּ֥נוּ חַיִּֽים׃

Moses summoned all Israel and said: “Hear, O Israel, the laws and the rules that I proclaim in your hearing today. Learn them and carefully observe them. The LORD our God made a covenant with us at Horeb. It was not with our ancestors that the LORD made this covenant, but with us—the living, every one of us who is here today.”

The introduction presents a complete educational process: hear, learn, guard, and do. The command שְׁמַע—“hear” is followed by the actions Israel must perform after hearing.

The word הַיּוֹם—“today” is characteristic of Deuteronomy. Moses presents the covenant not as a closed historical event belonging only to the past, but as a living reality that addresses every generation.

We also compared the forms דֹּבֵר—“speaking” and מְלַמֵּד—“teaching.” Speaking communicates words. Teaching explains, organizes, and prepares the listener to act.

The infinitive לַעֲשֹׂתָם—“to do them” completes the meaning of וּשְׁמַרְתֶּם—“you shall guard them.” Israel guards the commandments not by placing them at a distance, but by carrying them into practice.

Biblical Hebrew describes making a covenant with the expression כָּרַת בְּרִית—“cut a covenant.” We connected this expression with circumcision, the covenant between the pieces, the Passover sacrifice, and ancient Near Eastern covenant ceremonies in which animals were cut.

Cutting represented an action that could not simply be reversed. The divided animal could not be restored to its former condition. The ceremony therefore expressed the seriousness and permanence of entering a covenant.

Moses’ declaration—“It was not with our ancestors… but with us”—creates a deliberate tension. Historically, the covenant at Sinai was made forty years earlier with the generation that had left Egypt.

Yet Moses addresses their children as if they themselves had stood at Sinai. Through teaching, memory, and commitment, the covenant of the ancestors becomes the covenant of the living generation.

Deuteronomy 5:4–5

פָּנִ֣ים בְּפָנִ֗ים דִּבֶּ֨ר יְהֹוָ֧ה עִמָּכֶ֛ם
בָּהָ֖ר מִתּ֥וֹךְ הָאֵֽשׁ׃

אָנֹכִ֨י עֹמֵ֤ד בֵּין־יְהֹוָה֙ וּבֵ֣ינֵיכֶ֔ם בָּעֵ֥ת הַהִ֖וא
לְהַגִּ֥יד לָכֶ֛ם אֶת־דְּבַ֥ר יְהֹוָ֖ה
כִּ֤י יְרֵאתֶם֙ מִפְּנֵ֣י הָאֵ֔שׁ
וְלֹא־עֲלִיתֶ֥ם בָּהָ֖ר לֵאמֹֽר׃

“The LORD spoke with you face to face at the mountain from the fire. I stood between the LORD and you at that time to declare to you the word of the LORD, because you were afraid of the fire and did not go up the mountain.”

These verses create another important tension. God speaks to Israel “face to face,” yet Moses simultaneously stands between God and Israel.

Verse 5 functions almost like a parenthetical explanation. The people directly witnessed the revelation, but they also required Moses as a mediator because they feared the fire and did not ascend the mountain.

Exodus 20:19

וַיֹּֽאמְרוּ֙ אֶל־מֹשֶׁ֔ה דַּבֵּר־אַתָּ֥ה עִמָּ֖נוּ וְנִשְׁמָ֑עָה
וְאַל־יְדַבֵּ֥ר עִמָּ֛נוּ אֱלֹהִ֖ים
פֶּן־נָמֽוּת׃

“They said to Moses: You speak with us, and we will listen; but let God not speak with us, lest we die.”

According to Jewish tradition, Israel heard the first two commandments directly from God, while the remaining commandments were transmitted through Moses. This tradition preserves both sides of the biblical tension: direct national revelation and the essential role of Moses as mediator.

Central idea: Moses brings the new generation into the covenant by teaching them to experience Sinai as their own story. The revelation is described as direct, but it becomes livable through the mediation of Moses—the teacher who stands between the divine voice and the people.

Face to Face—Through Moses

Direct Revelation and the Role of the Mediator

After studying the covenant with the generation standing before Moses, we continued with Deuteronomy 5:4–5. These verses introduce an important tension at the heart of the revelation at Sinai: God speaks to Israel “face to face,” yet Moses simultaneously describes himself as standing between God and the people.

Deuteronomy 5:4–5

פָּנִ֣ים בְּפָנִ֗ים דִּבֶּ֨ר יְהֹוָ֧ה עִמָּכֶ֛ם
בָּהָ֖ר מִתּ֥וֹךְ הָאֵֽשׁ׃

“The LORD spoke with you face to face at the mountain from the fire. I stood between the LORD and you at that time, to declare to you the word of the LORD, because you were afraid of the fire and did not go up the mountain.”

We discussed how verse 5 functions almost like a parenthetical comment. Verse 4 presents the revelation as a direct encounter between God and the entire people. Verse 5 pauses the description and reminds the listener that Moses also stood between the two sides.

The people were therefore both direct witnesses to revelation and recipients of a message transmitted through Moses. They heard the divine voice and experienced the fire, but they were unable or unwilling to remain in direct contact with the overwhelming revelation.

The Book of Exodus explains that the people themselves asked Moses to become their intermediary.

Exodus 20:19

וַיֹּֽאמְרוּ֙ אֶל־מֹשֶׁ֔ה
דַּבֵּר־אַתָּ֥ה עִמָּ֖נוּ וְנִשְׁמָ֑עָה
וְאַל־יְדַבֵּ֥ר עִמָּ֛נוּ אֱלֹהִ֖ים
פֶּן־נָמֽוּת׃

“They said to Moses: You speak with us, and we will listen; but let God not speak with us, lest we die.”

Moses’ mediation is therefore not presented merely as a barrier placed between God and Israel. It is also the solution requested by the people themselves. The mediator makes it possible for them to continue receiving the revelation without being overwhelmed by it.

According to Jewish tradition, Israel heard the first two commandments directly from God, while the remaining commandments were transmitted through Moses. This tradition seeks to preserve both elements found in the biblical account: a direct national revelation and the essential role of Moses as intermediary.

We returned here to Moses’ role as teacher. A mediator does more than repeat words. Moses receives, communicates, explains, and prepares the people to live according to what they have heard.

Central idea: The revelation at Sinai is simultaneously direct and mediated. Israel encounters the divine voice, but Moses stands between God and the people so that revelation can be received, understood, and transformed into a way of life.

Two Versions of the Ten Commandments

Creation, Liberation, and the Changing Language of the Covenant

We read the Ten Commandments in Deuteronomy and compared them with the earlier version in Exodus. The central commandments remain recognizable, but the wording is not completely identical. The differences show that Deuteronomy is not a mechanical repetition of Exodus. Moses presents the commandments to a new generation and emphasizes ideas especially relevant to its future life in the Land.

We focused on two major examples: the commandment of the Sabbath and the commandment “You shall not covet.”

Remember and Observe the Sabbath

In Exodus, the Sabbath command begins with זָכוֹר—“remember.”

Exodus 20:8–11

זָכ֛וֹר אֶת־י֥וֹם הַשַּׁבָּ֖ת לְקַדְּשֽׁוֹ׃
שֵׁ֤שֶׁת יָמִים֙ תַּעֲבֹ֔ד
וְעָשִׂ֖יתָ כׇּל־מְלַאכְתֶּֽךָ׃

וְי֙וֹם֙ הַשְּׁבִיעִ֔י שַׁבָּ֖ת לַיהֹוָ֣ה אֱלֹהֶ֑יךָ
לֹֽא־תַעֲשֶׂ֨ה כׇל־מְלָאכָ֜ה אַתָּ֣ה וּבִנְךָ֣ וּבִתֶּ֗ךָ
עַבְדְּךָ֤ וַאֲמָֽתְךָ֙ וּבְהֶמְתֶּ֔ךָ
וְגֵרְךָ֖ אֲשֶׁ֥ר בִּשְׁעָרֶֽיךָ׃

כִּ֣י שֵֽׁשֶׁת־יָמִים֩ עָשָׂ֨ה יְהֹוָ֜ה
אֶת־הַשָּׁמַ֣יִם וְאֶת־הָאָ֗רֶץ אֶת־הַיָּם֙
וְאֶת־כׇּל־אֲשֶׁר־בָּ֔ם וַיָּ֖נַח בַּיּ֣וֹם הַשְּׁבִיעִ֑י
עַל־כֵּ֗ן בֵּרַ֧ךְ יְהֹוָ֛ה אֶת־י֥וֹם הַשַּׁבָּ֖ת וַֽיְקַדְּשֵֽׁהוּ׃

“Remember the Sabbath day and keep it holy. Six days you shall labor and do all your work, but the seventh day is a Sabbath of the LORD your God. You shall not do any work… For in six days the LORD made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy.”

Exodus grounds the Sabbath in creation. Human beings follow the divine pattern: six days of creation and work, followed by the seventh day of rest.

In Deuteronomy, the command begins with שָׁמוֹר—“observe” or “guard.”

Deuteronomy 5:12–15

שָׁמ֛וֹר אֶת־י֥וֹם הַשַּׁבָּ֖ת לְקַדְּשׁ֑וֹ
כַּאֲשֶׁ֥ר צִוְּךָ֖ יְהֹוָ֥ה אֱלֹהֶֽיךָ׃
שֵׁ֣שֶׁת יָמִ֣ים תַּעֲבֹד֮
וְעָשִׂ֣יתָ כׇּל־מְלַאכְתֶּךָ֒

וְי֨וֹם הַשְּׁבִיעִ֜י שַׁבָּ֣ת לַיהֹוָ֣ה אֱלֹהֶ֗יךָ
לֹ֣א תַעֲשֶׂ֣ה כׇל־מְלָאכָ֡ה אַתָּ֣ה וּבִנְךָֽ־וּבִתֶּ֣ךָ
וְעַבְדְּךָֽ־וַאֲמָתֶךָ וְכׇל־בְּהֶמְתֶּ֗ךָ וְגֵֽרְךָ֙
לְמַ֗עַן יָנ֛וּחַ עַבְדְּךָ֥ וַאֲמָתְךָ֖ כָּמֽוֹךָ׃

וְזָכַרְתָּ֗ כִּ֣י־עֶ֤בֶד הָיִ֙יתָ֙ בְּאֶ֣רֶץ מִצְרַ֔יִם
וַיֹּצִ֨אֲךָ֜ יְהֹוָ֤ה אֱלֹהֶ֙יךָ֙ מִשָּׁ֔ם
בְּיָ֥ד חֲזָקָ֖ה וּבִזְרֹ֣עַ נְטוּיָ֑ה
עַל־כֵּ֗ן צִוְּךָ֙ יְהֹוָ֣ה אֱלֹהֶ֔יךָ לַעֲשׂ֖וֹת אֶת־י֥וֹם הַשַּׁבָּֽת׃

“Observe the Sabbath day and keep it holy… The seventh day is a Sabbath of the LORD your God. You shall not do any work… so that your male and female servant may rest as you do. Remember that you were a slave in the land of Egypt and that the LORD your God brought you out from there with a mighty hand and an outstretched arm. Therefore the LORD your God commanded you to observe the Sabbath day.”

Deuteronomy gives the Sabbath a strongly social and ethical dimension. The command is not only that the Israelite household owner should rest. Servants, foreigners, and animals must also receive rest.

The explanation is based on the Exodus from Egypt: Israel must provide rest because Israel knows what it means to live as a slave whose time and labor belong to someone else.

At the original revelation at Sinai, the people had only recently left Egypt. The Exodus was their immediate experience and did not need to be retold at length. Forty years later, Moses turns that memory into a permanent social principle for the generation entering the Land.

We also distinguished between the Sabbath’s positive commandment and its negative commandment. Israel must sanctify the day, and Israel must refrain from labor. The Sabbath is both something to do and something not to do.

“You Shall Not Covet”

We then compared the final commandment in Exodus and Deuteronomy. The differences include the order of the wife and house, the separation of the wife from the other items, and the introduction of a second verb.

Exodus 20:17

לֹ֥א תַחְמֹ֖ד בֵּ֣ית רֵעֶ֑ךָ
לֹֽא־תַחְמֹ֞ד אֵ֣שֶׁת רֵעֶ֗ךָ וְעַבְדּ֤וֹ וַאֲמָתוֹ֙
וְשׁוֹר֣וֹ וַחֲמֹר֔וֹ
וְכֹ֖ל אֲשֶׁ֥ר לְרֵעֶֽךָ׃

“You shall not covet your neighbor’s house. You shall not covet your neighbor’s wife, male or female servant, ox or donkey, or anything that belongs to your neighbor.”

In Exodus, the house appears first. The wife, servants, animals, and other possessions then appear in the larger list describing the neighbor’s household.

Deuteronomy 5:21

וְלֹ֥א תַחְמֹ֖ד אֵ֣שֶׁת רֵעֶ֑ךָ
וְלֹ֨א תִתְאַוֶּ֜ה בֵּ֣ית רֵעֶ֗ךָ שָׂדֵ֜הוּ
וְעַבְדּ֤וֹ וַאֲמָתוֹ֙ שׁוֹר֣וֹ וַחֲמֹר֔וֹ
וְכֹ֖ל אֲשֶׁ֥ר לְרֵעֶֽךָ׃

“You shall not covet your neighbor’s wife. You shall not desire your neighbor’s house or field, male or female servant, ox or donkey, or anything that belongs to your neighbor.”

Deuteronomy places the wife before the house and gives her a separate clause. The text then changes from תַחְמֹד—“covet” to תִתְאַוֶּה—“desire” when referring to the house, field, servants, animals, and possessions.

This creates a clearer literary distinction between the wife and the household property. In Exodus, the sequence may give the impression that the wife belongs within the same general list as the house, servant, ox, and donkey. Deuteronomy separates her more clearly from that list.

At the same time, we emphasized that both versions belong to the social world of the ancient Near East. The assumptions of that world regarding women, household authority, marriage, property, and inheritance differ significantly from modern standards.

The difference should therefore not be described as full modern equality. Rather, Deuteronomy reorganizes the commandment in a way that distinguishes the wife more clearly from the material assets of the household.

Central idea: The two versions preserve the same covenantal structure, but they are not identical. Exodus emphasizes creation as the foundation of the Sabbath; Deuteronomy emphasizes liberation and social rest. In “You shall not covet,” Deuteronomy also changes the order and vocabulary, separating the wife more clearly from the household’s possessions.

Do Not Add and Do Not Take Away

The Limits of Teaching, Tradition, and Interpretation

We concluded with the principle of Bal Tosif—the prohibition against adding to or subtracting from the commandments. This creates a central tension in the lesson: Moses must teach, explain, and adapt the Torah for a new generation, but he must not replace the divine command with his own authority.

Deuteronomy 4:2

לֹ֣א תֹסִ֗פוּ עַל־הַדָּבָר֙ אֲשֶׁ֤ר אָנֹכִי֙ מְצַוֶּ֣ה אֶתְכֶ֔ם
וְלֹ֥א תִגְרְע֖וּ מִמֶּ֑נּוּ
לִשְׁמֹ֗ר אֶת־מִצְוֺת֙ יְהֹוָ֣ה אֱלֹהֵיכֶ֔ם
אֲשֶׁ֥ר אָנֹכִ֖י מְצַוֶּ֥ה אֶתְכֶֽם׃

“You shall not add to the word that I command you, nor shall you subtract from it, but you shall observe the commandments of the LORD your God that I command you.”

Deuteronomy 5:22

אֶת־הַדְּבָרִ֣ים הָאֵ֡לֶּה דִּבֶּר֩ יְהֹוָ֨ה אֶל־כׇּל־קְהַלְכֶ֜ם
בָּהָ֗ר מִתּ֤וֹךְ הָאֵשׁ֙ הֶעָנָ֣ן וְהָעֲרָפֶ֔ל
ק֥וֹל גָּד֖וֹל וְלֹ֣א יָסָ֑ף
וַֽיִּכְתְּבֵ֗ם עַל־שְׁנֵי֙ לֻחֹ֣ת אֲבָנִ֔ים וַֽיִּתְּנֵ֖ם אֵלָֽי׃

“The LORD spoke these words to your whole assembly at the mountain, from the fire, the cloud, and the thick darkness, with a great voice, and He added no more. He wrote them on two tablets of stone and gave them to me.”

The phrase וְלֹא יָסָף can mean that God “added no more,” or that the divine voice did not continue publicly. Together with Deuteronomy 4:2, it creates a literary frame around the Ten Commandments: the words are complete and must not be altered.

Deuteronomy 13:1 — English numbering: Deuteronomy 12:32

אֵ֣ת כׇּל־הַדָּבָ֗ר אֲשֶׁ֤ר אָנֹכִי֙ מְצַוֶּ֣ה אֶתְכֶ֔ם
אֹת֥וֹ תִשְׁמְר֖וּ לַעֲשׂ֑וֹת
לֹא־תֹסֵ֣ף עָלָ֔יו
וְלֹ֥א תִגְרַ֖ע מִמֶּֽנּוּ׃

“Everything that I command you, you shall carefully observe and perform. You shall not add to it, and you shall not subtract from it.”

We then compared this prohibition with the rabbinic instruction:

Pirkei Avot 1:1

מֹשֶׁה קִבֵּל תּוֹרָה מִסִּינַי וּמְסָרָהּ לִיהוֹשֻׁעַ…
הֱווּ מְתוּנִים בַּדִּין,
וְהַעֲמִידוּ תַלְמִידִים הַרְבֵּה,
וַעֲשׂוּ סְיָג לַתּוֹרָה.

“Moses received Torah from Sinai and transmitted it to Joshua… Be deliberate in judgment, raise many students, and make a fence around the Torah.”

A fence around the Torah is intended to protect a commandment from violation. The difficulty is determining when protection becomes alteration. Rabbinic tradition generally distinguishes between changing the biblical command itself and creating an openly identified protective regulation around it.

We also examined two New Testament passages that apply similar concerns in different ways:

Mark 7:8, 13: a human tradition must not replace or neutralize a divine command. The criticism is not necessarily directed against every tradition, but against a tradition that makes the commandment ineffective.
Revelation 22:18–19: the words of “the prophecy of this book” must not be expanded or diminished. The immediate reference is to the Book of Revelation itself, though later Christian readers often applied the warning more broadly.

Mark focuses on tradition replacing commandment. Revelation focuses on altering the words of a prophetic book. Deuteronomy focuses on preserving the commandments of the covenant.

Central question: How can a teacher explain and protect revelation without replacing it? The teacher must interpret enough to make the commandment livable—but must remain transparent about the difference between the original command and the later interpretive fence.
