As touching zeal (kata zhlo). So the old MSS. treating zhlo as neuter, not masculine. He was a zealot against Christianity, "persecuting the church" (diwkwn thn ekklhsian). He was the ringleader in the persecution from the death of Stephen till his own conversion ( Acts 8:1-9:9 ). Found blameless (genomeno amempto). "Having become blameless" ( Galatians 1:14 ). He knew and practised all the rules of the rabbis. A marvellous record, scoring a hundred in Judaism.
