Sarai and Hagar
1 aNow Sarai, Abram’s wife, had borne him no children. She had a female Egyptian servant whose name was bHagar.
Isaac’s Birth Promised
15 And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but Sarah1 shall be her name. 16 I will bless her, and moreover, I will cgive2 you a son by her. I will bless her, and dshe shall become nations; kings of peoples shall come from her.” 17 Then Abraham efell on his face fand 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 gSarah your wife shall bear you a son, and you shall call his name hIsaac.3 I will establish my covenant with him as an everlasting covenant for his offspring after him.
10 The Lord said, “I will surely return to you uabout this time next year, and vSarah your wife shall have a son.” And Sarah was listening at the tent door behind him. 11 Now wAbraham and Sarah were old, advanced in years. The way of women had ceased to be with Sarah. 12 xSo Sarah laughed to herself, saying, y“After I am worn out, and zmy 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 aIs anything too hard1 for the Lord? bAt the appointed time I will return to you, about this time next year, and Sarah shall have a son.”
