Genesis 17:2-5

17:2 Then I will confirm my covenant between me and you, and I will give you a multitude of descendants.”

17:3 Abram bowed down with his face to the ground, and God said to him, 17:4 “As for me, this is my covenant with you: You will be the father of a multitude of nations. 17:5 No longer will your name be Abram. Instead, your name will be Abraham because I will make you the father of a multitude of nations.
