Quit

kwit: Same derivation as "quiet," so that "to be quit" (Ex 21:19,28; Jos 2:20 the King James Version) is "to be relieved of responsibility," naqah, naqi, "guiltless" (so the Revised Version (British and American) Jos 2:20). Hence, "to quit one's self" means "to be freed by discharging a duty." The phrase in English Versions of the Bible, however, is a gloss for in 1Sa 4:9 it is used for hayah, "to be," while in 1Co 16:13 andrizomai, means "to behave like a man."
