Acts 16:1-4

1He also came to Derbe and to Lystra. A disciple named Timothy was there, the son of a Jewish woman who was a believer, but whose father was a Greek.

2The brothers in Lystra and Iconium spoke well of him.

3Paul wanted Timothy to accompany him, and he took him and circumcised him because of the Jews who were in those places, for they all knew that his father was Greek.

4As they went through the towns, they passed on the decrees that had been decided on by the apostles and elders in Jerusalem for the Gentile believers to obey.
