Then Abram fell on his face; and God said to him,
"Behold, my covenant is with you, and you shall be the father of a multitude of nations.
No longer shall your name be Abram, but your name shall be Abraham; for I have made you the father of a multitude of nations.
I will make you exceedingly fruitful; and I will make nations of you, and kings shall come forth from you.
And I will establish my covenant between me and you and your descendants after you throughout their generations for an everlasting covenant, to be God to you and to your descendants after you.
And I will give to you, and to your descendants after you, the land of your sojournings, all the land of Canaan, for an everlasting possession; and I will be their God."
And God said to Abraham, "As for you, you shall keep my covenant, you and your descendants after you throughout their generations.
This is my covenant, which you shall keep, between me and you and your descendants after you: Every male among you shall be circumcised.
You shall be circumcised in the flesh of your foreskins, and it shall be a sign of the covenant between me and you.
He that is eight days old among you shall be circumcised; every male throughout your generations, whether born in your house, or bought with your money from any foreigner who is not of your offspring,
both he that is born in your house and he that is bought with your money, shall be circumcised. So shall my covenant be in your flesh an everlasting covenant.
