13And the LORD said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old? 14Is 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. 15Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh. 16And the men rose up from thence, and looked toward Sodom: and Abraham went with them to bring them on the way.17And the LORD said, Shall I hide from Abraham that thing which I 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 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.
