'Deal Treacherously' in the Bible

Yea, none that wait on thee shall be ashamed: they shall be ashamed that deal treacherously without cause.

I beheld them that deal treacherously, and was grieved; because they kept not thy word.

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.

Yea, thou heardest not, yea, thou knewest not, yea, from of old thine ear was not opened; for I knew that thou wouldest ever deal treacherously, and thou wast called a transgressor from the womb.

Thou art of purer eyes than to behold evil, and canst not look on mischief: wherefore lookest thou upon them that deal treacherously, and keepest silence when the wicked swalloweth up a man more righteous than he?
