Acts 16:1-5

Now Paul also came 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 brothers and sisters who were in Lystra and Iconium.

Paul wanted this man to leave 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 ordinances for them to follow which had been determined by the apostles and elders in Jerusalem.

So the churches were being strengthened in the faith, and were increasing in number daily.
