Genesis 17:9-11

Wycliffe Bible

⁹ God said again to Abraham, And therefore thou shalt keep my covenant, and thy seed after thee, in their generations. (And God said to Abraham, And so thou shalt keep my covenant, thou, and thy descendants after thee, in all generations.)

¹⁰ This is my covenant, which ye shall keep, betwixt me and you, and thy seed after thee; each male kind of you shall be circumcised (every male among you shall be circumcised),

¹¹ and ye shall circumcise the flesh of your man’s rod, that it be into a sign of bond of peace betwixt me and you (so that it be a sign of the covenant between me and you).
