'Dealing' in the Bible

A hard vision hath been declared to me, The treacherous dealer is dealing treacherously, And the destroyer is destroying. Go up, O Elam, besiege, O Media, All its sighing I have caused to cease.

Woe, spoiler! and thou not spoiled, And treacherous! and they dealt not treacherously with thee, When thou dost finish, O spoiler, thou art spoiled, When thou dost finish dealing treacherously, They deal treacherously with thee.
