John 13:27

After the sop Satan entered into him.

We learn by comparison with the other accounts of this scene that the apostles each asked when Christ declared one should betray him, "Is it I?" Judas, who knew what he had sold himself to do, at last asked the same question and the Lord answered, "Thou hast said." It is evident from John 13:28, that this was answered in the ear of Judas and was not understood by his companions. Startled to know that his treachery was exposed to the Master, as soon as he receives the sop, he casts aside an hesitation and gives himself up wholly to Satan's work. This is what. understand by the statement, "Satan entered into him," for already he was under the devilish influence. Up to this time he had doubts and impulses to do better, but now he plunges headlong into the bottomless pit.

That thou doest, do quickly.

Judas understood these words. He was fully exposed. He had covenanted to do the wicked deed; Christ bids him do it at once. Christ wished the work done that night and he wished the traitor to leave at once that he might be alone to give. last sweet and loving charge to the faithful disciples.
