Genesis 17:9 WBT

⁷  And 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 to thee and to thy seed after thee.

⁸  And I will give to thee, and to thy seed after thee, the land in which thou art a stranger, all the land of Canaan, for an everlasting possession; and I will be their God.

⁹  And God said to Abraham, Thou shalt keep my covenant therefore, thou, and thy seed after thee, in their generations.

¹⁰  This [is] my covenant, which ye shall keep between me and you, and thy seed after thee; Every male-child among you shall be circumcised.

¹¹  And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant betwixt me and you.
