Satan entered into him. As it is certain that it was only at the instigation of Satan that Judas formed the design of committing so heinous a crime, why is it now said, for the first time, that Satan entered into him, who had already held the throne in his heart? But as they who are more fully confirmed in the faith which they formerly possessed are often said to believe, and thus an increase of their faith is called faith, so now that Judas is utterly given up to Satan, so as to be hurried on, by vehement impetuosity, to every extremity of evil, Satan is said to have entered into him. For as the saints make gradual progress, and in proportion to the new gifts by which they are continually enlarged, they are said to be filled with the Holy Spirit; so, in proportion as wicked men provoke the anger of God against themselves by their ingratitude, The Lord deprives them of his Spirit, of all light of reason, and, indeed, of all human feeling, and delivers them unreservedly to Satan. This is a dreadful vengeance of God, when men are given up to a reprobate mind, (Romans 1:28,) so that they scarcely differ at all from the brutes, and -- what is worse -- fall into horrid crimes from which the brutes themselves would shrink. We ought, therefore, to walk diligently in the fear of the Lord, lest, if we overpower his goodness by our wickedness, he at length give us up to the rage of, Satan. By giving the sop, Christ did not give an opportunity to Satan, but rather Judas, having received the sop, gave himself up entirely to Satan. It was, indeed, the occasion, but not the cause. His heart, which was harder than iron, ought to have been softened by so great kindness showed to him by Christ; and now his desperate and incurable obstinacy deserves that God, by his just judgment, should harden his heart still more by Satan. Thus, when, by acts of kindness to enemies, we heap coals of fire on their heads, (Romans 12:20,) if they are utterly incurable, they are the more enraged and inflamed [1] to their destruction. And yet no blame is due, on this account, to our kindness, by which their hearts ought to have been inflamed to love us. Augustine was wrong in thinking that this sop was an emblem of the body of Christ, since it was not during the Lord's Supper that it was given to Judas. It is also a very foolish dream to imagine that the devil entered essentially -- as the phrase is -- into Judas; for the Evangelist speaks only of the power and efficacy of Satan. This example reminds us what a dreadful punishment awaits all those who profane the gifts of the Lord by abusing them. What thou doest, do quickly. The exhortation addressed by Christ to Judas is not of such a nature that he can be regarded as exciting him to do the action: it is rather the language of one who views the crime with horror and detestation. [2] Hitherto he had endeavored, by various methods, to bring him back, but to no purpose. Now he addresses him as a desperate man, "Go to destruction, since you have resolved to go to destruction;" and, in doing so, he performs the office of a, judge, who condemns to death not those whom he, of his own accord, desires to ruin, but those who have already ruined themselves by their own fault. In short, Christ does not lay Judas under the necessity of perishing, but declares him to be what he had formerly been.

After the sop - After he had taken and probably eaten it. By this Judas saw that Jesus knew his design, and that he could not conceal his plan. He saw, also, that the other disciples would be acquainted with it; and, aroused by sudden anger, or with the apprehension that he should lose his reward, or that Jesus might escape, he resolved on executing his plan at once.
Satan entered into him - The devil had before this put it into his heart to betray Jesus John 13:2, but he now excited him to a more decided purpose. See Luke 22:3; also Acts 5:3; "Why hath Satan filled thine heart," etc.
What thou doest, do quickly - This showed to Judas that Jesus was acquainted with his design. He did not command him to betray him, but he left him to his own purpose. He had used means enough to reclaim him and lead him to a holy life, and now he brought him to a decision. He gave him to understand that he was acquainted with his plan, and submitted it to the conscience of Judas to do quickly what he would do. If he relented, he called on him to do it at once. If he could still pursue his wicked plan, could go forward when he was conscious that the Saviour knew his design, he was to do it at once. God adopts all means to bring men to a decision. He calls upon them to act decisively, firmly, immediately. He does not allow them the privilege to deliberate about wicked deeds, but calls on them to act at once, and to show whether they will obey or disobey him; whether they will serve him, or whether they will betray fits cause. He knows all their plans, as Jesus did that of Judas, and he calls on men to act under the full conviction that he knows all their soul. Sin thus is a vast evil. When men can sin knowing that God sees it all, it shows that the heart is fully set in them to do evil, and that there is nothing that will restrain them.

Satan entered into him - He had entered into him before, and now he enters again, to strengthen him in his purpose of delivering up his Master. But the morsel was not the cause of this entering in; the giving of it only marks the time in which the devil confirmed Judas in his traitorous purpose. Some have thought that this morsel was the sacrament of the Lord's Supper: but this is an utter mistake.
That thou doest, do quickly - As if he had said: "Thou art past all counsel; thou hast filled up the measure of thy iniquity, and hast wholly abandoned thyself to Satan; I will not force thee to turn from thy purpose, and without this thou wilt not. Thy designs are all known to me; what thou art determined to do, and I to permit, do directly; delay not, I am ready."

And after the sop, Satan entered into him,.... After he had taken and eaten the sop, or crust of bread, by which he was pointed out to be the betrayer, "Satan entered into him"; possessed his body, and filled his mind, and stirred him up more eagerly to pursue with rigour his wicked design. The Jews have a saying (l), that
"no man commits a transgression, until , "a spirit of madness enters into him".''
Such an evil spirit entered into Judas, which pushed him on to commit this horrid iniquity:
then said Jesus to him, that thou doest, do quickly; this he said, not as approving his wicked design, and exhorting him to it as a laudable action, but rather as deriding him, having nothing to care about, or fear from him; or as upbraiding him with his perfidy and wickedness, and signifying that he should take no methods to prevent him, though he fully knew what was in his heart to do; and it seems also to express the willingness of Christ, and his eager and hearty desire to suffer and die for his people, in order to obtain salvation for them.

after the sop Satan entered into him--Very solemn are these brief hints of the successive steps by which Judas reached the climax of his guilt. "The devil had already put it into his heart to betray his Lord." Yet who can tell what struggles he went through ere he brought himself to carry that suggestion into effect? Even after this, however, his compunctions were not at an end. With the thirty pieces of silver already in his possession, he seems still to have quailed--and can we wonder? When Jesus stooped to wash his feet, it may be the last struggle was reaching its crisis. But that word of the Psalm, about "one that ate of his bread who would lift up his heel against Him" (Psalm 41:9) probably all but turned the dread scale, and the still more explicit announcement, that one of those sitting with Him at the table should betray Him, would beget the thought, "I am detected; it is now too late to draw back." At that moment the sop is given; offer of friendship is once more made--and how affectingly! But already "Satan has entered into him," and though the Saviour's act might seem enough to recall him even yet, hell is now in his bosom, and he says within himself, "The die is cast; now let me go through with it"; fear, begone!" (See on Matthew 12:43).
Then said Jesus unto him, That thou doest, do quickly--that is, Why linger here? Thy presence is a restraint, and thy work stands still; thou hast the wages of iniquity, go work for it!

What thou doest, do quickly - This is not a permission, much less a command. It is only as if he had said, If thou art determined to do it, why dost thou delay? Hereby showing Judas, that he could not be hid, and expressing his own readiness to suffer.
