'Dealest' in the Bible

Bring my soul out of prison, that I may celebrate thy name. The righteous shall surround me, because thou dealest bountifully with me.

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.
