'Treacherously' in the Bible

A grievous vision is declared unto me: the treacherous dealeth treacherously, and the spoiler spoileth. Go up, Elam! besiege, Media! All the sighing thereof have I made to cease.

From the end of the earth have we heard songs: Glory to the righteous! And I said, My leanness, my leanness, woe unto me! The treacherous have dealt treacherously; yea, the treacherous have dealt very treacherously.

Woe to thee that spoilest, and thou wast not spoiled; and that dealest treacherously, and they dealt not treacherously with thee! When thou shalt cease to spoil, thou shalt be spoiled; when thou shalt make 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 wouldest ever deal treacherously, and thou wast called a transgressor from the womb.
