7And I will establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee. 8And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, all the land of Canaan, for an everlasting possession; and I will be their God. 9And God said unto Abraham, Thou shalt keep my covenant therefore, thou, and thy seed after thee in their generations. 10This is my covenant, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised.11And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant betwixt me and you. 12And he that is eight days old shall be circumcised among you, every man child in your generations, he that is born in the house, or bought with money of any stranger, which is not of thy seed. 13He that is born in thy house, and he that is bought with thy money, must needs be circumcised: and my covenant shall be in your flesh for an everlasting covenant.
