'Dealt' in the Bible

From the skirt of the earth we heard songs, The desire of the righteous. And I say, 'Leanness is to me, Leanness is to me, woe is to me.' Treacherous dealers dealt treacherously, Yea, treachery, treacherous dealers dealt treacherously.

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.
