'Treacherously' in the Bible

A grievous vision is declared unto me; the treacherous man dealeth treacherously, and the destroyer destroyeth. Go up, O Elam; besiege, O Media; all the sighing thereof have I made to cease.

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; yea, the treacherous have dealt very treacherously.

Woe to thee that destroyest, and thou wast not destroyed; and dealest treacherously, and they dealt not treacherously with thee! When thou hast ceased to destroy, thou shalt be destroyed; and when thou hast made an end of dealing treacherously, they shall deal treacherously with thee.

Yea, thou heardest not; yea, thou knewest not; yea, from of old thine ear was not opened: for I knew that thou didst deal very treacherously, and wast called a transgressor from the womb.
