“While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled.”
King James Version (KJV)
17:12 Those whom thou hast given me I have guarded, and none of them is lost, but the son of perdition - So one even of them whom God had given him is lost. So far was even that decree from being unchangeable! That the Scripture might be fulfilled - That is, whereby the Scripture was fulfilled. The son of perdition signifies one that deservedly perishes; as a son of death, #2Sam 12:5|; children of hell, #Mt 23:15|, and children of wrath, #Eph 2:3|, signify persons justly obnoxious to death, hell, wrath. #Psalm 109:8|.
Joh 17:12 None of them is lost, but the son of perdition. God had given him twelve; he had kept them in the name of the Father, and only one was lost, Judas, the traitor, the son of perdition, which the Scripture had predicted. See Ps 41:9.
