Genesis 18:16-22, 32-33

Then the men got up to leave and started out toward Sodom. Abraham walked along with them a short time to send them on their way. The LORD said, “Should I tell Abraham what I am going to do now? Abraham’s children will certainly become a great and powerful nation, and all nations on earth will be blessed through him. I have chosen him so he would command his children and his descendants to live the way the LORD wants them to, to live right and be fair. Then I, the LORD, will give Abraham what I promised him.” 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 said, “Lord, please don’t be angry with me, but let me bother you this one last time. What if you find ten there?” He said, “If I find ten there, I will not destroy it.” When the LORD finished speaking to Abraham, he left, and Abraham returned home.
