'Treacherous' in the Bible

A grievous vision is declared to me. The treacherous man deals treacherously, and the destroyer destroys. Go up, Elam; attack! I have stopped all of Media's sighing.

From the uttermost part of the earth have we heard songs. Glory to the righteous! But I said, "I pine away! I pine away! woe is me!" The treacherous have dealt treacherously. Yes, the treacherous have dealt very treacherously.
