Genesis 21:1-13

The Birth of Isaac

21:1 The Lord visited Sarah just as he had said he would and did for Sarah what he had promised. 21:2 So Sarah became pregnant and bore Abraham a son in his old age at the appointed time that God had told him. 21:3 Abraham named his son – whom Sarah bore to him – Isaac. 21:4 When his son Isaac was eight days old, Abraham circumcised him just as God had commanded him to do. 21:5 (Now Abraham was a hundred years old when his son Isaac was born to him.)

21:6 Sarah said, “God has made me laugh. Everyone who hears about this 10  will laugh 11  with me.” 21:7 She went on to say, 12  “Who would 13  have said to Abraham that Sarah would nurse children? Yet I have given birth to a son for him in his old age!”

21:8 The child grew and was weaned. Abraham prepared 14  a great feast on the day that Isaac was weaned. 15  21:9 But Sarah noticed 16  the son of Hagar the Egyptian – the son whom Hagar had borne to Abraham – mocking. 17  21:10 So she said to Abraham, “Banish 18  that slave woman and her son, for the son of that slave woman will not be an heir along with my son Isaac!”

21:11 Sarah’s demand displeased Abraham greatly because Ishmael was his son. 19  21:12 But God said to Abraham, “Do not be upset 20  about the boy or your slave wife. Do 21  all that Sarah is telling 22  you because through Isaac your descendants will be counted. 23  21:13 But I will also make the son of the slave wife into a great nation, for he is your descendant too.”


sn The Hebrew verb translated “visit” (פָּקַד, paqad ) often describes divine intervention for blessing or cursing; it indicates God’s special attention to an individual or a matter, always with respect to his people’s destiny. He may visit (that is, destroy) the Amalekites; he may visit (that is, deliver) his people in Egypt. Here he visits Sarah, to allow her to have the promised child. One’s destiny is changed when the Lord “visits.” For a more detailed study of the term, see G. André, Determining the Destiny (ConBOT).

tn Heb “and the Lord did.” The divine name has not been repeated here in the translation for stylistic reasons.

tn Heb “spoken.”

tn Or “she conceived.”

tn Heb “the one born to him, whom Sarah bore to him, Isaac.” The two modifying clauses, the first introduced with an article and the second with the relative pronoun, are placed in the middle of the sentence, before the name Isaac is stated. They are meant to underscore that this was indeed an actual birth to Abraham and Sarah in fulfillment of the promise.

tn Heb “Isaac his son, the son of eight days.” The name “Isaac” is repeated in the translation for clarity.

sn Just as God had commanded him to do. With the birth of the promised child, Abraham obeyed the Lord by both naming (Gen 17:19) and circumcising Isaac (17:12).

tn The parenthetical disjunctive clause underscores how miraculous this birth was. Abraham was 100 years old. The fact that the genealogies give the ages of the fathers when their first son is born shows that this was considered a major milestone in one’s life (G. J. Wenham, Genesis [WBC], 2:80).

tn Heb “Laughter God has made for me.”

10 tn The words “about this” are supplied in the translation for clarification.

11 sn Sarah’s words play on the name “Isaac” in a final triumphant manner. God prepared “laughter” (צְחֹק, ysÿkhoq ) for her, and everyone who hears about this “will laugh” (יִצְחַק, yitskhaq ) with her. The laughter now signals great joy and fulfillment, not unbelief (cf. Gen 18:12-15).

12 tn Heb “said.”

13 tn The perfect form of the verb is used here to describe a hypothetical situation.

14 tn Heb “made.”

15 sn Children were weaned closer to the age of two or three in the ancient world, because infant mortality was high. If an infant grew to this stage, it was fairly certain he or she would live. Such an event called for a celebration, especially for parents who had waited so long for a child.

16 tn Heb “saw.”

17 tn The Piel participle used here is from the same root as the name “Isaac.” In the Piel stem the verb means “to jest; to make sport of; to play with,” not simply “to laugh,” which is the meaning of the verb in the Qal stem. What exactly Ishmael was doing is not clear. Interpreters have generally concluded that the boy was either (1) mocking Isaac (cf. NASB, NIV, NLT) or (2) merely playing with Isaac as if on equal footing (cf. NAB, NRSV). In either case Sarah saw it as a threat. The same participial form was used in Gen 19:14 to describe how some in Lot’s family viewed his attempt to warn them of impending doom. It also appears later in Gen 39:14, 17, where Potiphar accuses Joseph of mocking them.

18 tn Heb “drive out.” The language may seem severe, but Sarah’s maternal instincts sensed a real danger in that Ishmael was not treating Isaac with the proper respect.

19 tn Heb “and the word was very wrong in the eyes of Abraham on account of his son.” The verb רָעַע (raa’) often refers to what is morally or ethically “evil.” It usage here suggests that Abraham thought Sarah’s demand was ethically (and perhaps legally) wrong.

20 tn Heb “Let it not be evil in your eyes.”

21 tn Heb “listen to her voice.” The idiomatic expression means “obey; comply.” Here her advice, though harsh, is necessary and conforms to the will of God. Later (see Gen 25), when Abraham has other sons, he sends them all away as well.

22 tn The imperfect verbal form here draws attention to an action that is underway.

23 tn Or perhaps “will be named”; Heb “for in Isaac offspring will be called to you.” The exact meaning of the statement is not clear, but it does indicate that God’s covenantal promises to Abraham will be realized through Isaac, not Ishmael.
