Acts 16:1-4 ASV

1 And he came also to Derbe and to Lystra: and behold, a certain disciple was there, named Timothy, the son of a Jewess that believed; but his father was a Greek.
2 The same was well reported of by the brethren that were at Lystra and Iconium.
3 Him would Paul have to go forth with him; and he took and circumcised him because of the Jews that were in those parts: for they all knew that his father was a Greek.
4 And as they went on their way through the cities, they delivered them the decrees to keep which had been ordained of the apostles and elders that were at Jerusalem.
