John 18:30 - Ellicott's Commentary On The Whole Bible

If he were not a malefactor, we would not have delivered him up unto thee. — They take the position that the Roman is the executive, and their own the judicial power. They bring no legal charge against Jesus, but assert, in effect that they themselves, who understood and had investigated the whole matter, had condemned Him to death, and that the fact that they had done so was in itself sufficient proof that He was worthy of death. They use the vague word “malefactor,” “evil-doer,” though in the trial before Caiaphas they had not sought to prove any evil deed, and they expect that upon this assertion Pilate will pronounce on Him, as on other malefactors, the sentence of death.
