“And he received the sign of circumcision, a seal of the righteousness of the faith which he had yet being uncircumcised: that he might be the father of all them that believe, though they be not circumcised; that righteousness might be imputed unto them also:”
King James Version (KJV)
4:11 And - After he was justified. He received the sign of circumcision - Circumcision, which was a sign or token of his being in covenant with God. A seal - An assurance on God's part, that he accounted him righteous, upon his believing, before he was circumcised. Who believe in uncircumcision - That is, though they are not circumcised.
Ro 4:11 He received the sign of circumcision. The outward mark in the flesh. A seal. A seal is often appended to a legal document as a proof. The covenant is made before the seal is annexed. Circumcision was not the covenant, but an outward mark of a covenant that before existed. The righteousness, of which it was a seal, had been acknowledged many years before. That he might be the father of all them that believe. Both Jews and Gentiles, circumcised and uncircumcised. The righteous, uncircumcised Abraham belonged to the latter class.
