Sirach (Ecclesiasticus) 11:30-33 Good News Bible Catholic Edition (GNBDK)

30. A proud person is a decoy to lure you into danger; like a spy, he will look for your weaknesses.

31. He will make good appear evil and find fault with the noblest actions.

32. A single spark can set a pile of coals ablaze, and a sinner is just waiting for a chance to use violence.

33. Watch out for such people and their evil plans; they will ruin you permanently.
