7 I will always keep the promise I have made to you and your descendants, because I am your God and their God.
8 I will give you and them the land in which you are now a foreigner. I will give the whole land of Canaan to your family forever, and I will be their God.
9 Abraham, you and all future members of your family must promise to obey me.
10-11 As the sign that you are keeping this promise, you must circumcise every man and boy in your family.
12-13 From now on, your family must circumcise every baby boy when he is eight days old. You must even circumcise any man or boy you have as a slave, both those born in your homes and those you buy from foreigners. This will be a sign that my promise to you will last forever.
14 Any man who isn't circumcised hasn't kept his part of the promise and cannot be one of my people.
15 Abraham, from now on your wife's name will be Sarah instead of Sarai.
