You know what I was like when I followed the Jewish religion—how I violently persecuted God’s church. I did my best to destroy it.

Galatians 1:13

For ye have heard of my conversation in time past in the Jews' religion, how that beyond measure I persecuted the church of God, and wasted it:

Galatians 1:13

Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.

John 8:44, Jesus speaking to the Jews

For there are many unruly and vain talkers and deceivers, specially they of the circumcision: whose mouths must be stopped, who subvert whole houses, teaching things which they ought not, for filthy lucre's sake. This witness is true. Wherefore rebuke them sharply, that they may be sound in the faith; not giving heed to Jewish fables, and commandments of men, that turn from the truth.

Titus 1:10‭-‬11‭, ‬13‭-‬14
