Renounce
New TestamentVine's Expository Dictionary of Biblical Words
Definition
1apeiponG550
lit., "to tell from" (apo, "from," eipon, an aorist form used to supply parts of lego, "to say"), signifies "to renounce," 2Co 4:2 (Middle Voice), of disowning "the hidden things of shame." In the Sept. of 1Ki 11:2 it signifies "to forbid," a meaning found in the papyri. The meaning "to renounce" may therefore carry with it the thought of forbidding the approach of the things disowned.
2apotassoG657
"to set apart, to appoint," a meaning found in the papyri (apo, from, tasso, "to arrange"), is used in the Middle Voice in the sense either of "taking leave of," e.g., Act 18:18, or "forsaking," Luk 14:33, RV, "renounceth" (AV "forsaketh"). See FORSAKE, LEAVE.
