Genesis 22:15-18

And the voice of the angel of the Lord came to Abraham a second time from heaven, Saying, I have taken an oath by my name, says the Lord, because you have done this and have not kept back from me your dearly loved only son, That I will certainly give you my blessing, and your seed will be increased like the stars of heaven and the sand by the seaside; your seed will take the land of those who are against them; And your seed will be a blessing to all the nations of the earth, because you have done what I gave you orders to do.
