And after the sop Satan entered into him. Then said Jesus unto him, That thou doest, do quickly.

People's New Testament

13:27 Satan entered into him. He gave himself up at once to Satan's purpose.

What thou doest, do quickly. Judas understood what these words meant, but no one else.

Wesley's Notes

13:27 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.

Jamieson-Fausset-Brown Bible Commentary

27-30. 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" (Ps 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 [1847]Mt 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!

Matthew Henry's Concise Commentary

13:18-30 Our Lord had often spoken of his own sufferings and death, without such trouble of spirit as he now discovered when he spake of Judas. The sins of Christians are the grief of Christ. We are not to confine our attention to Judas. The prophecy of his treachery may apply to all who partake of God's mercies, and meet them with ingratitude. See the infidel, who only looks at the Scriptures with a desire to do away their authority and destroy their influence; the hypocrite, who professes to believe the Scriptures, but will not govern himself by them; and the apostate, who turns aside from Christ for a thing of naught. Thus mankind, supported by God's providence, after eating bread with Him, lift up the heel against Him! Judas went out as one weary of Jesus and his apostles. Those whose deeds are evil, love darkness rather than light.
