Acts 8:13

Overview - Acts 8
By occasion of the persecution in Jerusalem, the church being planted in Samaria, by Philip the deacon, who preached, did miracles, and baptized many;
among the rest Simon the sorcerer, a great seducer of the people;
14 Peter and John come to confirm and enlarge the church; where, by prayer and imposition of hands giving the Holy Ghost;
18 when Simon would have bought the like power of them, Peter sharply reproving his hypocrisy and covetousness, and exhorting him to repentance, together with John preaching the word of the Lord, return to Jerusalem;
26 but the angel sends Philip to teach and baptize the Ethiopian Eunuch.

Acts 8:13  (King James Version)
Then Simon himself believed also: and when he was baptized, he continued with Philip, and wondered, beholding the miracles and signs which were done.

This Simon was probably, as several learned men suppose, the same who is mentioned by Josephus, as persuading Drusilla to leave her husband, and live with Felix.
