Genesis 18:17-19

17Then the Lord said, “Should I hide from Abraham what I am about to do?

18After all, Abraham will surely become a great and powerful nation, and all the nations on the earth will pronounce blessings on one another using his name.

19I have chosen him so that he may command his children and his household after him to keep the way of the Lord by doing what is right and just. Then the Lord will give to Abraham what he promised him.”
