Genesis 18
17 Ref And the Lord said, Am I to keep back from Abraham the knowledge of what I do;
18 Ref Seeing that Abraham will certainly become a great and strong nation, and his name will be used by all the nations of the earth as a blessing?
19 Ref For I have made him mine so that he may give orders to his children and those of his line after him, to keep the ways of the Lord, to do what is good and right: so that the Lord may do to Abraham as he has said.
