Acts 16:1-6

He came to Derbe and Lystra; and behold, a certain disciple was there, named Timothy, the son of a Jewess who believed, but his father was a Greek. The brothers who were at Lystra and Iconium gave a good testimony about him. Paul wanted to have him go out with him, and he took and circumcised him because of the Jews who were in those parts, for they all knew that his father was a Greek. As they went on their way through the cities, they delivered the decrees to them to keep which had been ordained by the apostles and elders who were at Jerusalem. So the assemblies were strengthened in the faith, and increased in number daily. When they had gone through the region of Phrygia and Galatia, they were forbidden by the Holy Spirit to speak the word in Asia.
