Genesis 17:6-9

I will make you exceedingly fruitful, and I will make nations of you, and kings will come from you. 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. [Gal 3:16] I will give to you and to your descendants after you the land in which you are a stranger [moving from place to place], all the land of Canaan, as an everlasting possession [of property]; and I will be their God.” [Acts 7:5] Further, God said to Abraham, “As for you [your part of the agreement], you shall keep and faithfully obey [the terms of] My covenant, you and your descendants after you throughout their generations.
