Genesis 18:16-25

Then the men got up from there, and looked toward Sodom; and Abraham walked with them to send them on the way. The LORD said, “Shall I keep secret from Abraham [My friend and servant] what I am going to do, [Gal 3:8] since Abraham is destined to become a great and mighty nation, and all the nations of the earth will be blessed through him? [Gen 12:2, 3] For I have known (chosen, acknowledged) him [as My own], so that he may teach and command his children and [the sons of] his household after him to keep the way of the LORD by doing what is righteous and just, so that the LORD may bring upon Abraham what He has promised him.” And the LORD said, “The outcry [of the sin] of Sodom and Gomorrah is indeed great, and their sin is exceedingly grave. I will go down now, and see whether they have acted [as vilely and wickedly] as the outcry which has come to Me [indicates]; and if not, I will know.” Now the [two] men (angelic beings) turned away from there and went toward Sodom, but Abraham remained standing before the LORD. Abraham approached [the LORD] and said, “Will You really sweep away the righteous (those who do right) with the wicked (those who do evil)? Suppose there are fifty righteous [people] within the city; will You really sweep it away and not spare it for the sake of the fifty righteous who are in it? Far be it from You to do such a thing—to strike the righteous with the wicked, so that the righteous and the wicked are treated alike. Far be it from You! Shall not the Judge of all the earth do right [by executing just and righteous judgment]?”
