'Dealt' in the Bible

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.
