'Of the Circumcision' in the Bible

Until some men arrived from James, he was in the habit of eating with the gentiles, but after those men came, he withdrew from the gentiles and would not associate with them any longer, because he was afraid of the circumcision party.

Jesus, who is called Justus, also greets you. These are the only ones of the circumcision who are fellow workers for the kingdom of God. They have been an encouragement to me.
