Acts 16:1-4

1Then he came to Derbe and Lystra: and, behold, a certain disciple was there, named Timothy, the son of a certain woman, who was a Jewess, and believed; but his father was a Greek:

2Who was well reported of by the brethren that were at Lystra and Iconium.

3Him would Paul have to go forth with him; and took and circumcised him because of the Jews who were in those quarters: for they all knew that his father was a Greek.

4And as they went through the cities, they delivered to them the decrees to keep, that were ordained by the apostles and elders who were at Jerusalem.
