John 13:26

He it is to whom I shall give a sop— See the note on Matthew 26:23. The word rendered sop, ψωμιον, implies the lower crust, or a piece broken off the lower crust of bread; it is often used for a morsel, or a few crumbs of bread. From the kind and smallness of the piece which was offered him, as well as from its being dipped in the sauce, described in the note above referred to, it is probable that Jesus put it into the traitor's mouth; for to cut a morsel, and dip it in sauce, is the action of one who is going either to put it in his own mouth, or into the mouth of another. Perhaps Judas might have some suspicion that Christ's giving him the sop was designed to mark him out as the person he spoke of; and was the more furiously enraged against him: however, Satan, seeing this to be a fit opportunity to execute the villanous design, worked more in this son of perdition now than ever before; and, leading him captive at his will, prevailed upon him to set about it without delay.
