Acts 22:4

And I said, Lord, they know that I imprisoned and beat in every synagogue them that believed on thee: And when the blood of thy martyr Stephen was shed, I also was standing by, and consenting unto his death, and kept the raiment of them that slew him.

Who was before a blasphemer, and a persecutor, and injurious: but I obtained mercy, because I did it ignorantly in unbelief. And the grace of our Lord was exceeding abundant with faith and love which is in Christ Jesus. This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief.

I verily thought with myself, that I ought to do many things contrary to the name of Jesus of Nazareth. Which thing I also did in Jerusalem: and many of the saints did I shut up in prison, having received authority from the chief priests; and when they were put to death, I gave my voice against them. And I punished them oft in every synagogue, and compelled them to blaspheme; and being exceedingly mad against them, I persecuted them even unto strange cities.

For I am the least of the apostles, that am not meet to be called an apostle, because I persecuted the church of God.

And Saul was consenting unto his death. And at that time there was a great persecution against the church which was at Jerusalem; and they were all scattered abroad throughout the regions of Judea and Samaria, except the apostles. And devout men carried Stephen to his burial, and made great lamentation over him. As for Saul, he made havock of the church, entering into every house, and haling men and women committed them to prison. Therefore they that were scattered abroad went every where preaching the word.

The same followed Paul and us, and cried, saying, These men are the servants of the most high God, which shew unto us the way of salvation.

And he began to speak boldly in the synagogue: whom when Aquila and Priscilla had heard, they took him unto them, and expounded unto him the way of God more perfectly.

And the same time there arose no small stir about that way.

But when divers were hardened, and believed not, but spake evil of that way before the multitude, he departed from them, and separated the disciples, disputing daily in the school of one Tyrannus.

But this I confess unto thee, that after the way which they call heresy, so worship I the God of my fathers, believing all things which are written in the law and in the prophets:

And cast him out of the city, and stoned him: and the witnesses laid down their clothes at a young man’s feet, whose name was Saul.

And Saul, yet breathing out threatenings and slaughter against the disciples of the Lord, went unto the high priest, And desired of him letters to Damascus to the synagogues, that if he found any of this way, whether they were men or women, he might bring them bound unto Jerusalem.

Then Ananias answered, Lord, I have heard by many of this man, how much evil he hath done to thy saints at Jerusalem: And here he hath authority from the chief priests to bind all that call on thy name.

But all that heard him were amazed, and said; Is not this he that destroyed them which called on this name in Jerusalem, and came hither for that intent, that he might bring them bound unto the chief priests?

Concerning zeal, persecuting the church; touching the righteousness which is in the law, blameless.
