Genesis 17:8-10

Amplified Bible

⁸ 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.”^(A)

⁹ 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. ¹⁰ This is [the sign of] My covenant, which you shall keep and faithfully obey, between Me and you and your descendants after you: Every male among you shall be circumcised.
