Then the lawless one will be revealed, whom the Lord will kill with the breath of his mouth, and bring to nothing by the brightness of his coming;
and shall destroy with the brightness of his coming: The words "shall destroy" (katargeo) mean "to render idle, unemployed, inactive, inoperative" (Thayer 336-1-2673). Thayer says the word "brightness" (epiphania) means "an appearing, appearance" (245-2-2015). Coming (paraousia) means "the presence of one coming, hence the coming, arrival, advent" (Thayer 490-2-3952).
