Genesis 18:19

17 And the LORD said, “Shall I hide from Abraham what I am about to do?

18 Abraham will surely become a great and powerful nation, and through him all the nations of the earth will be blessed.

For I have chosen him, so that he will command his children and his household after him to keep the way of the LORD by doing what is right and just, in order that the LORD may bring upon Abraham what He has promised.”

20 Then the LORD said, “The outcry against Sodom and Gomorrah is great. Because their sin is so grievous,

21 I will go down to see if their actions fully justify the outcry that has reached Me. If not, I will find out.”

Do read the surrounding verses too, because the context often says more than a single verse.
