rwp@Matthew:16:26 @{Gain} (\kerdsi\) and {profit} (\zmithi\). Both aorist subjunctives (one active, the other passive) and so punctiliar action, condition of third class, undetermined, but with prospect of determination. Just a supposed case. The verb for "forfeit" occurs in the sense of being fined or mulcted of money. Songs:the papyri and inscriptions. {Exchange} (\antallagma\). As an exchange, accusative in apposition with \ti\. The soul has no market price, though the devil thinks so. "A man must give, surrender, his life, and nothing less to God; no \antallagma\ is possible" (McNeile). This word \antallagma\ occurs twice in the _Wisdom of Sirach_: "There is no exchange for a faithful friend" (6:15); "There is no exchange for a well-instructed soul" (26:14).
