Genesis 17:12-13

New American Standard Bible

¹² And every male among you who is ^(A)eight days old shall be circumcised throughout your generations, including a slave who is born in the house or who is bought with money from any foreigner, who is not of your ^[a]descendants. ¹³ A slave who is born in your house or ^(B)who is bought with your money shall certainly be circumcised; so My covenant shall be in your flesh as an everlasting covenant.
