Genesis 17:15-17

17:15 Then God said to Abraham, “As for your wife, you must no longer call her Sarai; ¹  Sarah ²  will be her name. 17:16 I will bless her and will give you a son through her. I will bless her and she will become a mother of nations. ³  Kings of countries ⁴  will come from her!”

17:17 Then Abraham bowed down with his face to the ground and laughed ⁵  as he said to himself, ⁶  “Can ⁷  a son be born to a man who is a hundred years old? ⁸  Can Sarah ⁹  bear a child at the age of ninety?” ¹⁰ 

Ephesians 2:11-12

New Life Corporately

2:11 Therefore remember that formerly you, the Gentiles in the flesh – who are called “uncircumcision” by the so-called “circumcision” that is performed on the body ¹¹  by human hands – 2:12 that you were at that time without the Messiah, ¹²  alienated from the citizenship of Israel and strangers to the covenants of promise, ¹³  having no hope and without God in the world.

[17:15]  ¹ tn Heb “[As for] Sarai your wife, you must not call her name Sarai, for Sarah [will be] her name.”

[17:15]  ² sn Sarah. The name change seems to be a dialectical variation, both spellings meaning “princess” or “queen.” Like the name Abram, the name Sarai symbolized the past. The new name Sarah, like the name Abraham, would be a reminder of what God intended to do for Sarah in the future.

[17:16]  ³ tn Heb “she will become nations.”

[17:16]  ⁴ tn Heb “peoples.”

[17:17]  ⁵ sn Laughed. The Hebrew verb used here provides the basis for the naming of Isaac: “And he laughed” is וַיִּצְחָק (vayyitskhaq); the name “Isaac” is יִצְחָק (yitskhaq), “he laughs.” Abraham’s (and Sarah’s, see 18:12) laughter signals disbelief, but when the boy is born, the laughter signals surprise and joy.

[17:17]  ⁶ tn Heb “And he fell on his face and laughed and said in his heart.”

[17:17]  ⁷ tn The imperfect verbal form here carries a potential nuance, as it expresses the disbelief of Abraham.

[17:17]  ⁸ tn Heb “to the son of a hundred years.”

[17:17]  ⁹ sn It is important to note that even though Abraham staggers at the announcement of the birth of a son, finding it almost too incredible, he nonetheless calls his wife Sarah, the new name given to remind him of the promise of God (v. 15).

[17:17]  ¹⁰ tn Heb “the daughter of ninety years.”

[2:11]  ¹¹ tn Grk “in the flesh.”

[2:12]  ¹² tn Or “without Christ.” Both “Christ” (Greek) and “Messiah” (Hebrew and Aramaic) mean “one who has been anointed.” Because the context refers to ancient Israel’s messianic expectation, “Messiah” was employed in the translation at this point rather than “Christ.”

[2:12]  ¹³ tn Or “covenants of the promise.”
