Genesis 18:16-22, 32-33

Then the men rose from there and looked toward Sodom, and Abraham went with them to send them on the way. And the LORD said, “Shall I hide from Abraham what I am doing, since Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him? For I have known him, in order that he may command his children and his household after him, that they keep the way of the LORD, to do righteousness and justice, that the LORD may bring to Abraham what He has spoken to him.” And the LORD said, “Because the outcry against Sodom and Gomorrah is great, and because their sin is very grave, I will go down now and see whether they have done altogether according to the outcry against it that has come to Me; and if not, I will know.” Then the men turned away from there and went toward Sodom, but Abraham still stood before the LORD.

Then he said, “Let not the Lord be angry, and I will speak but once more: Suppose ten should be found there?” And He said, “I will not destroy it for the sake of ten.” So the LORD went His way as soon as He had finished speaking with Abraham; and Abraham returned to his place.
