Galatians 1:13; Galatians 1:23; Galatians 4:21

13 For you have heard of my former manner of life in Judaism, how I used to persecute the church of God beyond measure and tried to destroy it;
23 but only, they kept hearing, "He who once persecuted us is now preaching the faith which he once tried to destroy."
21 Tell me, you who want to be under law, do you not listen to the law?
