Forfeit - Vine's Expository Dictionary of New Testament Words
Forfeit
[ 1,,G2210, zemioo ]in the Active Voice, signifies to damage;" in the Passive, "to suffer loss, forfeit," Matthew 16:26; Mark 8:36, of the "life," RV; AV, and RV marg., "soul;" in each place the RV has "forfeit," for AV, "lose;" Luke 9:25, "his own self" (RV. "forfeit," AV, "be cast away;" here the preceding word "lose" translates apollumi, "to destroy"). What is in view here is the act of "forfeiting" what is of the greatest value, not the casting away by Divine judgment, though that is involved, but losing or penalizing one's own self, with spiritual and eternal loss. The word is also used in 1 Corinthians 3:15; 2 Corinthians 7:9; Philippians 3:8. See CAST, LOSE, LOSS (suffer).
