Acts 16:1-3

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.
