Genesis 18:16-21

16And the men rose up from thence, and looked toward Sodom: and Abraham went with them to bring them on the way. 17And Yhwh 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 Yhwh, to do justice and judgment; that Yhwh may bring upon Abraham that which he hath spoken of him. 20And Yhwh said, Because the cry of Sodom and Gomorrah is great, and because their sin is very grievous; 21I will go down now, and see whether they have done altogether according to the cry of it, which is come unto me; and if not, I will know.
