Genesis 18:17-19

Complete Jewish Bible

¹⁷ Adonai said, “Should I hide from Avraham what I am about to do, ¹⁸ inasmuch as Avraham is sure to become a great and strong nation, and all the nations of the earth will be blessed by him? ¹⁹ For I have made myself known to him, so that he will give orders to his children and to his household after him to keep the way of Adonai and to do what is right and just, so that Adonai may bring about for Avraham what he has promised him.”
