Genesis 17:10-12

21st Century King James Version

¹⁰ This is My covenant which ye shall keep between Me and you and thy seed after thee: every manchild among you shall be circumcised.

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

¹² And he that is eight days old shall be circumcised among you, every manchild in your generations, he that is born in the house or bought with money from any stranger who is not of thy seed.
