Romans 4:11

“And he received the sign of circumcision, etc..] Or “the sign circumcision”, as the Syriac version reads it, and so the Alexandrian copy, and two of Stephens's; that is, Abraham received at the hands of God, the commandment of circumcision, which was a “sign” or token of the covenant; not of grace, but of that peculiar covenant God made with Abraham and his natural seed, concerning their enjoyment of the land of Canaan; and which was a distinctive sign or badge, which distinguished the posterity of Abraham from other people, and was also a typical one; not of baptism, for circumcision was peculiar to Abraham's natural seed, whereas baptism is not, but was administered to Gentiles as well as…”

“And he received the sign ... - A sign is that by which any thing is shown, or represented. And circumcision thus showed that there was a covenant between Abraham and God; Genesis 17:1-10. It became the public mark or token of the relation which he sustained to God. A seal - See the note at John 3:33. A seal is that mark of wax or other substance, which is attached to an instrument of writing, as a deed, etc., to confirm, ratify it, or to make it binding. Sometimes instruments were sealed, or made authentic by stamping on them some word, letter, or device, which had been engraved on silver, or on precious stones. The seal or stamp was often worn as an ornament on the finger; Esther 8:8;…”

“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. Romans 4:12”

“4:11-12 When God instituted circumcision, he called it “a sign of the covenant” between himself and Abraham (Gen 17:11). The covenant was already in place (Gen 12:1-3; 15:1-21; 17:1-8) even before Abraham was circumcised (Gen 17:9-14). This shows that the covenant was based on faith, not circumcision. So Abraham is the spiritual father of all people, whether circumcised (Jews) or uncircumcised (Gentiles), who have the same kind of faith Abraham had—that is, faith in God’s promises (Rom 4:13-25).”
