acts 22:3 I am verily a man which am a Jew, born in Tarsus, a city in Cilicia, yet brought up in this city at the feet of Gamaliel, and taught according to the perfect manner of the law of the fathers, and was zealous toward God, as ye all are this day. - Free Bible Online

      3. a Jew of Tarsus, brought up in this city, at the feet--(See on Lu 10:39).
      of Gamaliel--(See on Ac 5:34); a fact of great importance in the apostle's history, standing in the same relation to his future career as Moses' education in the Egyptian court to the work for which he was destined.
      the perfect manner of the law of the fathers--the strictest form of traditional Judaism.
      zealous--"a zealot."
      toward God as ye all are this day--his own former murderous zeal against the disciples of the Lord Jesus being merely reflected in their present treatment of himself.
