de-sev'-a-b'-l-nes, de-sev' (nasha', "to lead astray"): "The pride of thy heart hath deceived thee" (Jer 49:16), i.e. "Thy stern mountain fastnesses have persuaded thee that thou art impregnable." In Jer 20:7, "O Lord, thou hast deceived me, and I was deceived," pathah, signifies "to be enticed," "persuaded," as in the American Standard Revised Version and the Revised Version, margin.
In the Old Testament most often, and in the New Testament regularly, the various words rendered in the King James Version "deceive" denote some deliberate misleading in the moral or spiritual realm. False prophets (Jer 29:8), false teachers (Eph 5:6) and Satan himself (Re 12:9) are deceivers in this sense. In the gospels, the King James Version "deceive" (planao, 9 times Mt 24:4-5 parallel Mr 13:5-6 parallel Lu 21:8; Mt 24:11,24; Joh 7:12,47) becomes in the Revised Version (British and American) "lead astray"; the same change is made in 1Jo 2:26; 3:7; but elsewhere (13 t) both the King James Version and the Revised Version (British and American) render planao by "deceive."
"Deceivableness" (apate), only in 2Th 2:10, signifies power to deceive, not liability to deception; the Revised Version (British and American) "deceit."
