Acts 16:3-5 (New International Version)

³Paul wanted to take him along on the journey, so he circumcised him because of the Jews who lived in that area, for they all knew that his father was a Greek. ⁴As they traveled from town to town, they delivered the decisions reached by the apostles and elders in Jerusalem for the people to obey. ⁵So the churches were strengthened in the faith and grew daily in numbers.
