Thayer's Greek Lexicon
ἀντάλλαγμα, ἀνταλλαγτος, τό (ἀντί in place of, in turn, and ἄλλαγμα see ἀλλάσσω), "that which is given in place of another thing by way of exchange; what is given either in order to keep or to acquire anything": Mat_16:26; Mar_8:37, where the sense is, 'nothing equals in value the soul's salvation.' Christ transfers a proverbial expression respecting the supreme value of the natural life (Homer, Iliad 9, 401 οὐ γάρ ἐμοί ψυχῆς ἀνταξιον) to the life eternal. (Rth_4:7; Jer_15:13; Sir_6:15, etc.; Euripides, Or. 1157; Josephus, b. j. 1, 18, 3.)
