Acts 16:1-4

Paul came also to Derbe and to Lystra. And a disciple was there, named Timothy, the son of a Jewish woman who was a believer, but his father was a Greek, and he was well spoken of by the brethren who were in Lystra and Iconium. Paul wanted this man to go with him; and he took him and circumcised him because of the Jews who were in those parts, for they all knew that his father was a Greek. Now while they were passing through the cities, they were delivering the decrees which had been decided upon by the apostles and elders who were in Jerusalem, for them to observe.
