Acts 16:1-3
Then came he to Derbe and Lystra: and, behold, a
certain disciple was there, named Timotheus, the son of a certain woman,
which was a Jewess, and believed; but his father was a Greek:
Which was well reported of by the brethren that were at Lystra and Iconium.
Him
would Paul have to go forth with him; and took and circumcised him
because of the Jews which were in those quarters: for they knew all that
his father was a Greek.
