Romans 4:11-12

New King James Version

¹¹ And ^(A)he received the sign of circumcision, a seal of the righteousness of the faith which he had while still uncircumcised, that ^(B)he might be the father of all those who believe, though they are uncircumcised, that righteousness might be imputed to them also, ¹² and the father of circumcision to those who not only are of the circumcision, but who also walk in the steps of the faith which our father ^(C)Abraham had while still uncircumcised.
