Genesis 22:11; Genesis 22:15-18

11 But the angel of the LORD called to him from heaven and said, "Abraham, Abraham!" And he said, "Here I am."

15 Then the angel of the LORD called to Abraham a second time from heaven,

16 and said, "By Myself I have sworn, declares the LORD , because you have done this thing and have not withheld your son, your only son,

17 indeed I will greatly bless you, and I will greatly multiply your seed as the stars of the heavens and as the sand which is on the seashore ; and your seed shall possess the gate of their enemies.

18 "In your seed all the nations of the earth shall be blessed, because you have obeyed My voice."
