¹⁵ So ^(A)Hagar bore Abram a son; and Abram named his son, whom Hagar bore, Ishmael.

¹⁵ Then God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but ^[a]Sarah shall be her name. ¹⁶ And I will bless her ^(A)and also give you a son by her; then I will bless her, and she shall be a mother ^(B)of nations; ^(C)kings of peoples shall be from her.”

¹⁷ Then Abraham fell on his face ^(D)and laughed, and said in his heart, “Shall a child be born to a man who is one hundred years old? And shall Sarah, who is ninety years old, bear a child?” ¹⁸ And Abraham ^(E)said to God, “Oh, that Ishmael might live before You!”

¹⁹ Then God said: “No, ^(F)Sarah your wife shall bear you a son, and you shall call his name Isaac; I will establish My ^(G)covenant with him for an everlasting covenant, and with his descendants after him.

¹⁰ And He said, “I will certainly return to you ^(A)according to the time of life, and behold, ^(B)Sarah your wife shall have a son.”

(Sarah was listening in the tent door which was behind him.)

Isaac Is Born^(A)

21 And the Lord ^(B)visited Sarah as He had said, and the Lord did for Sarah ^(C)as He had spoken.

²⁸ Now ^(A)we, brethren, as Isaac was, are ^(B)children of promise.

¹¹ By faith ^(A)Sarah herself also received strength to conceive seed, and ^(B)she^[a] bore a child when she was past the age, because she judged Him ^(C)faithful who had promised.
