Acts 16:1-5 NIV

[1] Paul came to Derbe and then to Lystra, where a disciple named Timothy lived, whose mother was Jewish and a believer but whose father was a Greek. [2] The believers at Lystra and Iconium spoke well of him. [3] Paul 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. [4] As they traveled from town to town, they delivered the decisions reached by the apostles and elders in Jerusalem for the people to obey. [5] So the churches were strengthened in the faith and grew daily in numbers.
