'Dealeth' in the Bible

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

The wicked findeth favour, He hath not learned righteousness, In a land of straightforwardness he dealeth perversely, And seeth not the excellency of Jehovah.
