Genesis 17:5-11

YLT(i) 5 and thy name is no more called Abram, but thy name hath been Abraham, for father of a multitude of nations have I made thee; 6 and I have made thee exceeding fruitful, and made thee become nations, and kings go out from thee.
7 `And I have established My covenant between Me and thee, and thy seed after thee, to their generations, for a covenant age-during, to become God to thee, and to thy seed after thee; 8 and I have given to thee, and to thy seed after thee, the land of thy sojournings, the whole land of Canaan, for a possession age-during, and I have become their God.' 9 And God saith unto Abraham, `And thou dost keep My covenant, thou and thy seed after thee, to their generations; 10 this is My covenant which ye keep between Me and you, and thy seed after thee: Every male of you is to be circumcised; 11 and ye have circumcised the flesh of your foreskin, and it hath become a token of a covenant between Me and you.
