Genesis 21:2-5

21:2 So Sarah became pregnant ¹  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. ²  21:4 When his son Isaac was eight days old, ³  Abraham circumcised him just as God had commanded him to do. ⁴  21:5 (Now Abraham was a hundred years old when his son Isaac was born to him.) ⁵ 

Joshua 24:2-3

24:2 Joshua told all the people, “Here is what the Lord God of Israel says: ‘In the distant past your ancestors ⁶  lived beyond the Euphrates River, ⁷  including Terah the father of Abraham and Nahor. They worshiped ⁸  other gods, 24:3 but I took your father Abraham from beyond the Euphrates ⁹  and brought him into ¹⁰  the entire land of Canaan. I made his descendants numerous; I gave him Isaac,

Joshua 24:1

Israel Renews its Commitment to the Lord

24:1 Joshua assembled all the Israelite tribes at Shechem. He summoned Israel’s elders, rulers, judges, and leaders, and they appeared before God.

Joshua 1:1

The Lord Commissions Joshua

1:1 After Moses the Lord’s servant died, the Lord said to Joshua son of Nun, Moses’ assistant:

Isaiah 51:2

51:2 Look at Abraham, your father,

and Sarah, who gave you birth. ¹¹ 

When I summoned him, he was a lone individual, ¹² 

but I blessed him ¹³  and gave him numerous descendants. ¹⁴ 

Luke 3:34

3:34 the son of Jacob, the son of Isaac, the son of Abraham, the son of Terah, ¹⁵  the son of Nahor,

Acts 7:8

7:8 Then God ¹⁶  gave Abraham ¹⁷  the covenant ¹⁸  of circumcision, and so he became the father of Isaac and circumcised him when he was eight days old, ¹⁹  and Isaac became the father of ²⁰  Jacob, and Jacob of the twelve patriarchs. ²¹ 

Romans 9:7-9

9:7 nor are all the children Abraham’s true descendants; rather “through Isaac will your descendants be counted.” ²²  9:8 This means ²³  it is not the children of the flesh ²⁴  who are the children of God; rather, the children of promise are counted as descendants. 9:9 For this is what the promise declared: ²⁵  “About a year from now ²⁶  I will return and Sarah will have a son.” ²⁷ 

Hebrews 11:11

11:11 By faith, even though Sarah herself was barren and he was too old, ²⁸  he received the ability to procreate, ²⁹  because he regarded the one who had given the promise to be trustworthy.

Hebrews 11:17-18

11:17 By faith Abraham, when he was tested, offered up Isaac. He had received the promises, ³⁰  yet he was ready to offer up ³¹  his only son. 11:18 God had told him, “Through Isaac descendants will carry on your name,” ³² 

[21:2]  ¹ tn Or “she conceived.”

[21:3]  ² 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.

[21:4]  ³ tn Heb “Isaac his son, the son of eight days.” The name “Isaac” is repeated in the translation for clarity.

[21:4]  ⁴ 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).

[21:5]  ⁵ 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).

[24:2]  ⁶ tn Heb “your fathers.”

[24:2]  ⁷ tn Heb “the river,” referring to the Euphrates. This has been specified in the translation for clarity.

[24:2]  ⁸ tn Or “served.”

[24:3]  ⁹ tn Heb “the river,” referring to the Euphrates. This has been specified in the translation for clarity.

[24:3]  ¹⁰ tn Or “through.”

[51:2]  ¹¹ sn Although Abraham and Sarah are distant ancestors of the people the prophet is addressing, they are spoken of as the immediate parents.

[51:2]  ¹² tn Heb “one”; NLT “was alone”; TEV “was childless.”

[51:2]  ¹³ tn “Bless” may here carry the sense of “endue with potency, reproductive power.” See Gen 1:28.

[51:2]  ¹⁴ tn Heb “and I made him numerous.”

[3:34]  ¹⁵ sn The list now picks up names from Gen 11:10-26; 5:1-32; 1 Chr 1:1-26, especially 1:24-26.

[7:8]  ¹⁶ tn Grk “he”; the referent (God) has been specified in the translation for clarity.

[7:8]  ¹⁷ tn Grk “him”; the referent (Abraham) has been specified in the translation for clarity.

[7:8]  ¹⁸ sn God gave…the covenant. Note how the covenant of promise came before Abraham’s entry into the land and before the building of the temple.

[7:8]  ¹⁹ tn Grk “circumcised him on the eighth day,” but many modern readers will not understand that this procedure was done on the eighth day after birth. The temporal clause “when he was eight days old” conveys this idea more clearly. See Gen 17:11-12.

[7:8]  ²⁰ tn The words “became the father of” are not in the Greek text due to an ellipsis, but must be supplied for the English translation. The ellipsis picks up the verb from the previous clause describing how Abraham fathered Isaac.

[7:8]  ²¹ sn The twelve patriarchs refers to the twelve sons of Jacob, the famous ancestors of the Jewish race (see Gen 35:23-26).

[9:7]  ²² tn Grk “be called.” The emphasis here is upon God’s divine sovereignty in choosing Isaac as the child through whom Abraham’s lineage would be counted as opposed to Ishmael.

[9:8]  ²³ tn Grk “That is,” or “That is to say.”

[9:8]  ²⁴ tn Because it forms the counterpoint to “the children of promise” the expression “children of the flesh” has been retained in the translation.

[9:9]  ²⁵ tn Grk “For this is the word of promise.”

[9:9]  ²⁶ tn Grk “About this time I will return.” Since this refers to the time when the promised child would be born, it would be approximately a year later.

[9:9]  ²⁷ sn A quotation from Gen 18:10, 14.

[11:11]  ²⁸ tn Grk “past the time of maturity.”

[11:11]  ²⁹ tn Grk “power to deposit seed.” Though it is not as likely, some construe this phrase to mean “power to conceive seed,” making the whole verse about Sarah: “by faith, even though Sarah herself was barren and too old, she received ability to conceive, because she regarded the one who had given the promise to be trustworthy.”

[11:17]  ³⁰ tn Here “received the promises” refers to the pledges themselves, not to the things God promised.

[11:17]  ³¹ tn Grk “he was offering up.” The tense of this verb indicates the attempt or readiness to sacrifice Isaac without the actual completion of the deed.

[11:18]  ³² tn Grk “in Isaac seed will be named for you.”
