Romans 4
10 Ref How then was it reckoned? when he was in circumcision, or in uncircumcision? Not in circumcision, but in uncircumcision:
11 Ref 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;
