Romans 4:10-12

American Standard Version

¹⁰ How then was it reckoned? when he was in circumcision, or in uncircumcision? Not in circumcision, but in uncircumcision: ¹¹ and he received the sign of circumcision, a seal of the righteousness of the faith which he had while he was in uncircumcision: that he might be the father of all them that believe, though they be in uncircumcision, that righteousness might be reckoned unto them; ¹² and the father of circumcision to them who not only are of the circumcision, but who also walk in the steps of that faith of our father Abraham which he had in uncircumcision.
