15 God also said to Abraham, “As for Sarai(A) your wife, you are no longer to call her Sarai; her name will be Sarah.(B) 16 I will bless her and will surely give you a son by her.(C) I will bless her so that she will be the mother of nations;(D) kings of peoples will come from her.”

17 Abraham fell facedown;(E) he laughed(F) and said to himself, “Will a son be born to a man a hundred years old?(G) Will Sarah bear a child at the age of ninety?”(H) 18 And Abraham said to God, “If only Ishmael(I) might live under your blessing!”(J)

19 Then God said, “Yes, but your wife Sarah will bear you a son,(K) and you will call him Isaac.[a](L) I will establish my covenant with him(M) as an everlasting covenant(N) for his descendants after him. 20 And as for Ishmael, I have heard you: I will surely bless him; I will make him fruitful and will greatly increase his numbers.(O) He will be the father of twelve rulers,(P) and I will make him into a great nation.(Q) 21 But my covenant(R) I will establish with Isaac, whom Sarah will bear to you(S) by this time next year.”(T) 22 When he had finished speaking with Abraham, God went up from him.(U)

  1. Genesis 17:19 Isaac means he laughs.

“Where is your wife Sarah?”(A) they asked him.

“There, in the tent,(B)” he said.

10 Then one of them said, “I will surely return to you about this time next year,(C) and Sarah your wife will have a son.”(D)

Now Sarah was listening at the entrance to the tent, which was behind him. 11 Abraham and Sarah were already very old,(E) and Sarah was past the age of childbearing.(F) 12 So Sarah laughed(G) to herself as she thought, “After I am worn out and my lord(H) is old, will I now have this pleasure?”

13 Then the Lord said to Abraham, “Why did Sarah laugh and say, ‘Will I really have a child, now that I am old?’(I) 14 Is anything too hard for the Lord?(J) I will return to you at the appointed time next year,(K) and Sarah will have a son.”(L)

15 Sarah was afraid, so she lied and said, “I did not laugh.”

But he said, “Yes, you did laugh.”

The Birth of Isaac

21 Now the Lord was gracious to Sarah(A) as he had said, and the Lord did for Sarah what he had promised.(B) Sarah became pregnant and bore a son(C) to Abraham in his old age,(D) at the very time God had promised him.(E) Abraham gave the name Isaac[a](F) to the son Sarah bore him. When his son Isaac was eight days old, Abraham circumcised him,(G) as God commanded him. Abraham was a hundred years old(H) when his son Isaac was born to him.

Sarah said, “God has brought me laughter,(I) and everyone who hears about this will laugh with me.”
