Genesis 18:9 And they said unto him, Where is Sarah thy wife? And he said, Behold, in the tent.

9 And they said unto him, Where is Sarah thy wife? And he said, Behold, in the tent. 10 And he said, I will certainly return unto thee according to the time of life; and, lo, Sarah thy wife shall have a son. And Sarah heard it in the tent door, which was behind him. 11 Now Abraham and Sarah were old and well stricken in age; and it ceased to be with Sarah after the manner of women. 12 Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also? 13 And the LORD said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old? 14 Is any thing too hard for the LORD? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son. 15 Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh. 16 And the men rose up from thence, and looked toward Sodom: and Abraham went with them to bring them on the way. 17 And the LORD said, Shall I hide from Abraham that thing which I do; 18 Seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him? 19 For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD, to do justice and judgment; that the LORD may bring upon Abraham that which he hath spoken of him.
