So when Peter went up to Jerusalem, the circumcised believers took issue with him,

The circumcised believers who had accompanied Peter were greatly astonished that the gift of the Holy Spirit had been poured out even on the Gentiles,

Then God gave Abraham the covenant of circumcision, and so he became the father of Isaac and circumcised him when he was eight days old, and Isaac became the father of Jacob, and Jacob of the twelve patriarchs.
