Advantage

ad-van'-taj (cakhan): In Job 35:3 is interpreted in succeeding clause as "profit." In Ro 3:1 perissos, is likewise interpreted by a paraphrase in the next sentence. the Revised Version (British and American) prefers to render pleonekteo by "take advantage," where the King James Version has "defraud" (2Co 7:2), or "make gain of" (2Co 12:17; compare 2Co 2:11). In Jude 1:16 "advantage" (opheleia) means "profit."
