Acts 16:1-3

Young's Literal Translation

16 And he came to Derbe and Lystra, and lo, a certain disciple was there, by name Timotheus son of a certain woman, a believing Jewess, but of a father, a Greek,

² who was well testified to by the brethren in Lystra and Iconium;

³ this one did Paul wish to go forth with him, and having taken [him], he circumcised him, because of the Jews who are in those places, for they all knew his father -- that he was a Greek.
