'Circumcised' in the Bible

Later, God gave Abraham the covenant of circumcision. Later, he fathered Isaac and circumcised him on the eighth day. Then Isaac fathered Jacob, and Jacob fathered the twelve patriarchs.

Then the circumcised believers who had come with Peter were amazed that the gift of the Holy Spirit had been poured out on the gentiles, too,

Then some men came down from Judea and started to teach the brothers, "Unless you are circumcised according to the Law of Moses, you can't be saved."

But some believers from the party of the Pharisees stood up and said, "The gentiles must be circumcised and ordered to keep the Law of Moses."

Paul wanted this man to go with him, so he took him and had him circumcised because of the Jews who lived in that region, since everyone knew that Timothy's father was a Greek.
