Those whom You gave Me I have kept; and none of them is lost except the son of perdition, that the Scripture might be fulfilled.  (John 17:12)

Jesus prays in respect of twelve men, those the heavenly Father gave into his care, and he reflects that he discharged his duty even to Judas, who he calls the ‘son of perdition’.  Judas he ‘lost’; and the translation is of the Koine Greek verb, ἀπόλλυμι apollumi, which is formed from the prefix apo, ‘away from’, and ollymi, ‘to destroy’, thus, ‘to utterly destroy after being cut away’.

Judas hanged himself and, in circumstances that are tantamount to the bathetic, ‘falling headlong, he burst open in the middle and all his entrails gushed out’, Acts 1:18.
