ENORMITY

e-nor'-mi-ti: The marginal rendering in the King James Version of Hosea 6:9 for "lewdness," and in the Revised Version (British and American) of Leviticus 18:17; 19:29; 20:14 for "wickedness." In each case it is the translation of zimmah, meaning originally, "thought" or "plot," mostly in a bad sense, lewdness, wickedness; in Lev it is unnatural wickedness--incest.
