Genesis 18:17-19

17Then the Lord said to himself, ‘I should tell Abraham what I have decided to do.

18Abraham's descendants will become a great nation of people. They will be very powerful. Through him, I will bless all the nations of the earth.

19I have chosen him so that he will teach my message to his children and their families. He will teach them to do what is right and what is fair. Then I, the Lord, will do for Abraham everything that I have promised to him.’
