13 But the Lord said to Abraham: “Why did Sarah laugh and say, ‘Will I really bear a child, old as I am?’
14 Is anything too marvelous for the Lord to do? At the appointed time, about this time next year, I will return to you, and Sarah will have a son.”
15 Sarah lied, saying, “I did not laugh,” because she was afraid. But he said, “Yes, you did.”
16 With Abraham walking with them to see them on their way, the men set out from there and looked down toward Sodom.
17 The Lord considered: Shall I hide from Abraham what I am about to do,
18 now that he is to become a great and mighty nation, and all the nations of the earth are to find blessing in him?
19 Indeed, I have singled him out that he may direct his children and his household in the future to keep the way of the Lord by doing what is right and just, so that the Lord may put into effect for Abraham the promises he made about him.
