Acts 16:1-3

¹And he came to Derbe and Lystra. And behold, there was a certain disciple there named Timothy, the son of a Jewish woman that believed; but his father was a Gentile.

²To this man the brethren that were in Lystra and Iconium, gave a good testimony.

³Him Paul would have to go along with him: and taking him he circumcised him, because of the Jews who were in those places. For they all knew that his father was a Gentile.
