Acts 16:1-3

1 And he came to Derbe and Lystra: and there was a certain disciple there named Timothy, whose mother was one of the Jews of the faith, but his father was a Greek;

2 Of whom the brothers at Lystra and Iconium had a high opinion.

3 Paul had a desire for him to go with him, and he gave him circumcision because of the Jews who were in those parts: for they all had knowledge that his father was a Greek.
