'Dealt' in the Bible

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.
