Genesis 18:8-19
English Standard Version
9They said to him, "Where is Sarah your wife?" And he said, "She is in the tent."
10The Lord said, "I will surely return to you about this time next year, and Sarah your wife shall have a son." And Sarah was listening at the tent door behind him.
11Now Abraham and Sarah were old, advanced in years. The way of women had ceased to be with Sarah.
12So Sarah laughed to herself, saying, "After I am worn out, and my lord is old, shall I have pleasure?"
13The Lord said to Abraham, "Why did Sarah laugh and say, ‘Shall I indeed bear a child, now that I am old?’
14Is anything too hard for the Lord? At the appointed time I will return to you, about this time next year, and Sarah shall have a son."
15But Sarah denied it, saying, "I did not laugh," for she was afraid. He said, "No, but you did laugh."
16Then the men set out from there, and they looked down toward Sodom. And Abraham went with them to set them on their way.
17The Lord said, "Shall I hide from Abraham what I am about to do,
18seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him?
19For I have chosen him, that he may command his children and his household after him to keep the way of the Lord by doing righteousness and justice, so that the Lord may bring to Abraham what he has promised him."
