Genesis 18:20-26

Then the LORD said, “I have heard many complaints against the people of Sodom and Gomorrah. They are very evil. I will go down and see if they are as bad as I have heard. If not, I will know.” So the men turned and went toward Sodom, but Abraham stood there before the LORD. Then Abraham approached him and asked, “Do you plan to destroy the good people along with the evil ones? What if there are fifty good people in that city? Will you still destroy it? Surely you will save the city for the fifty good people living there. Surely you will not destroy the good people along with the evil ones; then they would be treated the same. You are the judge of all the earth. Won’t you do what is right?” The LORD said, “If I find fifty good people in the city of Sodom, I will save the whole city because of them.”
