'Dealing' in the Bible

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.

And they act deceitfully every one with his neighbour, and speak not the truth: they teach their tongue to speak falsehood, they weary themselves with perverse dealing.
