Ishmael and Isaac: Two Sons Under Threat
Genesis 21–22 · The Torah Readings of Rosh Hashanah
Why does Jewish tradition place the story of Ishmael on the first day of Rosh Hashanah and the Binding of Isaac on the second?
In this lesson we read Genesis 21 and Genesis 22 side by side. The two narratives contain striking similarities: Abraham’s sons are placed in danger, Abraham acts with remarkable speed, a divine messenger intervenes, and both stories ultimately move from the possibility of death toward a renewed future.
Video 1 · Introduction
Why These Two Stories on Rosh Hashanah?
We begin with the two possible themes considered for this Rosh Hashanah lesson and with the special Torah readings of the holiday.
Our focus is the relationship between the stories of Ishmael and Isaac. Rather than treating Genesis 21 and Genesis 22 as completely separate narratives, we ask what becomes visible when they are read together.
The comparison opens larger questions about judgment, responsibility, divine election, human action, and the universal dimension of Rosh Hashanah.
It also prepares us for the pattern that will guide the rest of the lesson: we will move back and forth between the two stories, paying attention both to their striking similarities and to the important differences between them.
Video 2 · Genesis 21:12–13
Isaac Is Chosen — Ishmael Is Not Abandoned
The story begins with a difficult distinction. God confirms that the covenantal line will continue through Isaac:
כִּי בְיִצְחָק יִקָּרֵא לְךָ זָרַע
“For through Isaac shall offspring be called yours.”
Yet the very next verse refuses to erase Ishmael:
וְגַם אֶת־בֶּן־הָאָמָה לְגוֹי אֲשִׂימֶנּוּ כִּי זַרְעֲךָ הוּא
“And I will also make the son of the slave woman into a nation, because he is your offspring.”
Isaac has a unique covenantal role, but Ishmael remains Abraham’s זֶרַע — offspring and receives his own divine promise. The biblical text therefore distinguishes between election and abandonment: choosing Isaac does not mean that Ishmael ceases to matter.
Hebrew Focus
We examine the syntax of the passage, the biblical construction used to express a negative command, the different functions of כִּי, and the root ק־ר־א in the phrase יִקָּרֵא לְךָ זָרַע.

Abraham Rises Early — Ishmael Is Sent Away
We now begin following the literary parallels between the two stories more closely. In Genesis 21, Abraham responds immediately to the difficult instruction concerning Hagar and Ishmael:
וַיַּשְׁכֵּם אַבְרָהָם בַּבֹּקֶר
“Abraham rose early in the morning.”
This wording will return almost verbatim in the story of Isaac. The repetition creates an important literary bridge between the two narratives: in both cases, Abraham rises early in the morning and begins a journey that places one of his sons in danger.
Biblical Hebrew Focus
We examine the characteristic narrative sequence of Biblical Hebrew and the frequent use of wayyiqtol forms to move the story forward step by step.
We also discuss the phonological behavior of Hebrew consonants in forms where a consonant carries a silent shewa, and why certain consonants resist or affect the expected doubling represented by a dagesh.

The Same Morning — The Second Son
Genesis 22 deliberately returns us to language we have just encountered in the story of Ishmael:
וַיַּשְׁכֵּם אַבְרָהָם בַּבֹּקֶר
Again, Abraham “rose early in the morning.” This time, however, he does not send a son away with his mother. Abraham himself accompanies Isaac toward the place God has commanded him to go.
The similarity in wording makes the difference between the stories even more visible. Ishmael is sent away from Abraham; Isaac travels with Abraham. Yet both journeys begin with the same father, the same urgency, and almost exactly the same Hebrew phrase.
Biblical Hebrew Focus
We continue examining the chain of wayyiqtol verbs that drives Biblical Hebrew narrative forward.
We also focus on the root ח־ב־ש in the verb describing Abraham saddling his donkey, and explore how the root can express ideas of binding, fastening, wrapping, or preparing something for use. We compare this semantic development with similar changes in meaning found in English words.

Ishmael at the Edge of Death
The water runs out in the wilderness, and the danger to Ishmael becomes immediate. Hagar places the boy beneath a bush and moves away because she cannot bear to watch him die:
אַל־אֶרְאֶה בְּמוֹת הַיָּלֶד
“Let me not see the boy die.”
This is the first of the two Rosh Hashanah narratives to bring one of Abraham’s sons to the threshold of death. Hagar’s response is deeply human: she distances herself because she cannot watch what she believes is about to happen.
Biblical Hebrew Focus
We continue identifying the wayyiqtol forms that structure the sequence of events.
We also examine the root כ־ל־ה, used when the water is exhausted, and its relationship to the broader Hebrew idea of reaching an end or completion. This leads to a discussion of related Hebrew vocabulary built around the concepts of completion, finishing, and perfection.
The phrase אַל־אֶרְאֶה also returns us to the biblical method of expressing a negative command or wish.
Video 6 · Genesis 22:9–10
Isaac at the Edge of Death
We now return to Isaac. Once again, one of Abraham’s sons reaches the point at which death appears imminent. But the difference between the two stories is striking.
Hagar withdrew because she could not watch Ishmael die. In the Akedah, Abraham himself builds the altar, arranges the wood, binds Isaac, places him on the altar, and reaches for the knife.
וַיַּעֲקֹד אֶת־יִצְחָק בְּנוֹ
The verb translated “he bound” gives the story its traditional Hebrew name: עֲקֵדַת יִצְחָק — the Binding of Isaac.
Biblical Hebrew Focus
We discuss עָקַד as a rare biblical word and its significance as a hapax legomenon in this verbal form and context.
We also continue tracing the dense sequence of wayyiqtol verbs. The grammar emphasizes Abraham’s extraordinary activity: he does not delegate the preparations. He performs action after action himself.
Finally, we examine the word מַאֲכֶלֶת, the knife Abraham takes in his hand, and its relationship to the root א־כ־ל, “to eat.”
Video 7 · Genesis 21:17–18
God Hears Ishmael
At the moment when Ishmael appears closest to death, the story suddenly changes direction:
וַיִּשְׁמַע אֱלֹהִים אֶת־קוֹל הַנַּעַר
“God heard the voice of the boy.”
The wording is especially significant because the name יִשְׁמָעֵאל — Ishmael itself expresses the idea that God hears. In the moment of greatest danger, the narrative effectively enacts the meaning of his name.
The messenger then addresses Hagar with a sequence of feminine singular commands:
קוּמִי · שְׂאִי · הַחֲזִיקִי
“Rise · lift · hold.”
The boy who seems to have no future is immediately given one:
כִּי־לְגוֹי גָּדוֹל אֲשִׂימֶנּוּ
“For I will make him into a great nation.”
This promise takes us back to the beginning of the story, where God had already said concerning Ishmael:
לְגוֹי אֲשִׂימֶנּוּ כִּי זַרְעֲךָ הוּא
The crisis has not cancelled the promise. Ishmael remains Abraham’s offspring, and his rescue restores the future that God had already promised him.
Biblical Hebrew Focus
We examine the root ש־מ־ע in the verb וַיִּשְׁמַע and in the name יִשְׁמָעֵאל, and then look at the feminine imperative forms קוּמִי, שְׂאִי, הַחֲזִיקִי.
Video 8 · Genesis 21:19 · Genesis 22:11–13
Two Rescues — Hearing, Seeing, and a Future
In the final section, we bring the two stories together. Isaac, like Ishmael, reaches the moment when death appears imminent. And again, divine intervention comes at the last possible moment.
In Genesis 22, a messenger calls to Abraham:
וַיִּקְרָא אֵלָיו מַלְאַךְ יְהֹוָה מִן־הַשָּׁמַיִם
“A messenger of the LORD called to him from heaven.”
This echoes the rescue of Ishmael, where a messenger likewise called to Hagar מִן־הַשָּׁמַיִם — from heaven.
Hagar Sees the Well
After God hears Ishmael, Hagar’s eyes are opened:
וַיִּפְקַח אֱלֹהִים אֶת־עֵינֶיהָ וַתֵּרֶא בְּאֵר מָיִם
“God opened her eyes, and she saw a well of water.”
The woman who had just said אַל־אֶרְאֶה בְּמוֹת הַיָּלֶד — “Let me not see the boy die” now sees the very thing that allows him to live.
Abraham Sees the Ram
Immediately after Isaac is spared, Abraham also sees the means of rescue:
וַיִּשָּׂא אַבְרָהָם אֶת־עֵינָיו וַיַּרְא וְהִנֵּה־אַיִל
“Abraham lifted his eyes and saw — there was a ram.”
The parallel is striking. In one story, Hagar sees water and Ishmael lives. In the other, Abraham sees a ram and Isaac lives.
Reading the Two Stories Together
- Abraham rises early in the morning in both stories.
- One of Abraham’s sons is placed in mortal danger.
- The danger reaches its most extreme point before God intervenes.
- A divine messenger calls from heaven.
- Seeing becomes part of the rescue.
- The threatened child survives and receives a future.
But the differences remain just as important. Hagar cannot bear to watch Ishmael die, while Abraham actively raises the knife over Isaac. Ishmael is sent away from Abraham, while Isaac walks beside him. Isaac carries the covenantal line, while Ishmael receives a different national destiny.
