³⁶ And Sarah my master's wife ^(A)bore a son to my master when she was old, and ^(B)to him he has given all that he has.

^5 (A)Abraham gave all he had to Isaac.

¹⁰ So she said to Abraham, ^(A)“Cast out this slave woman with her son, for the son of this slave woman shall not be heir with my son Isaac.”

The Birth of Isaac

21 The Lord ^(A)visited Sarah as he had said, and the Lord did to Sarah ^(B)as he had promised. ² And Sarah ^(C)conceived and bore Abraham a son in his old age ^(D)at the time of which God had spoken to him. ³ Abraham called the name of his son who was born to him, whom Sarah bore him, ^(E)Isaac.^{[a] 4} And Abraham ^(F)circumcised his son Isaac when he was eight days old, ^(G)as God had commanded him. ^5 (H)Abraham was a hundred years old when his son Isaac was born to him. ⁶ And Sarah said, ^(I)“God has made laughter for me; everyone who hears will laugh over me.” ⁷ And she said, “Who would have said to Abraham that Sarah would nurse children? ^(J)Yet I have borne him a son in his old age.”

¹⁹ He did not weaken in faith when he considered his own body, which was ^(A)as good as dead (^(B)since he was about a hundred years old), or when he considered ^(C)the barrenness^[a] of Sarah's womb.

¹⁰ The Lord said, “I will surely return to you ^(A)about this time next year, and ^(B)Sarah your wife shall have a son.” And Sarah was listening at the tent door behind him. ¹¹ Now ^(C)Abraham and Sarah were old, advanced in years. The way of women had ceased to be with Sarah. ^12 (D)So Sarah laughed to herself, saying, ^(E)“After I am worn out, and ^(F)my lord is old, shall I have pleasure?” ¹³ The Lord said to Abraham, “Why did Sarah laugh and say, ‘Shall I indeed bear a child, now that I am old?’ ^14 (G)Is anything too hard^[a] for the Lord? ^(H)At the appointed time I will return to you, about this time next year, and Sarah shall have a son.”

Isaac's Birth Promised

¹⁵ And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but Sarah^[a] shall be her name. ¹⁶ I will bless her, and moreover, I will ^(A)give^[b] you a son by her. I will bless her, and ^(B)she shall become nations; kings of peoples shall come from her.” ¹⁷ Then Abraham ^(C)fell on his face ^(D)and laughed and said to himself, “Shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?” ¹⁸ And Abraham said to God, “Oh that Ishmael might live before you!” ¹⁹ God said, “No, but ^(E)Sarah your wife shall bear you a son, and you shall call his name ^(F)Isaac.^[c] I will establish my covenant with him as an everlasting covenant for his offspring after him.

²⁹ And Abram and Nahor took wives. The name of Abram's wife was ^(A)Sarai, and the name of Nahor's wife, ^(B)Milcah, the daughter of Haran the father of Milcah and Iscah. ³⁰ Now Sarai was barren; she had no child.
