ψευδοπροφητῶν, [5 verses] (noun pl masc gen) "False prophets" is pseudoprophētēs. which means a "false" or "lying" prophet, which means "one who speaks for a god and interprets his will," "interpreter," "keepers of the oracle," "the highest level of priesthood in Egypt," and "herald." In the Septuagint, this word is used to translated the Hebrew nabiy' (נָבִיא), which is the same word translated as "prophet." It seems to have been used to separate Israel's true prophets from those the Septuagint translators saw as pretenders.  -- "False prophets" from a hybrid Greek word that means "lying interpreters of god's will" or "fake interpreters." This Greek word appears for the first time in the Septuagint, the Greek OT.
