Acts 16:1-3

1Paul 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.

2The believers at Lystra and Iconium spoke well of him.

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.
