UNTOWARD

un-to'-erd, un-tord' (skolios): Appears only in Acts 2:40, the King James Version "Save yourselves from this untoward generation." It means "perverse," "willful," "crooked," and is so translated in Revised Version: "this crooked generation" (apo tes geneas tes skolias tautes). the King James Version headings to Isaiah 28 and Hosea 6 have "untowardness." This now obsolete term probably derived its orgin from the idea of the heart that was not inclined toward the divine will and teaching. Hence, "not-toward," or "untoward."
