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)

⁶ So Abraham hurried into the tent to Sarah. “Quick,” he said, “get three seahs^[a] of the finest flour and knead it and bake some bread.”^(A)

⁷ Then he ran to the herd and selected a choice, tender calf^(B) and gave it to a servant, who hurried to prepare it. ⁸ He then brought some curds^(C) and milk^(D) and the calf that had been prepared, and set these before them.^(E) While they ate, he stood near them under a tree.

⁹ “Where is your wife Sarah?”^(F) they asked him.

“There, in the tent,^(G)” he said.

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

Now Sarah was listening at the entrance to the tent, which was behind him. ¹¹ Abraham and Sarah were already very old,^(J) and Sarah was past the age of childbearing.^{(K) 12} So Sarah laughed^(L) to herself as she thought, “After I am worn out and my lord^(M) 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?’^{(N) 14} Is anything too hard for the Lord?^(O) I will return to you at the appointed time next year,^(P) and Sarah will have a son.”^(Q)

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

But he said, “Yes, you did laugh.”

¹¹ And by faith even Sarah, who was past childbearing age,^(A) was enabled to bear children^(B) because she^[a] considered him faithful^(C) who had made the promise.
