Matthew 27:5

Then Judas, who had betrayed Him, when he saw that Jesus had been condemned, repented, and returned the thirty pieces of silver to the chief priests and elders, saying, I have sinned in that I have betrayed innocent blood. And they said, What is that …

He hung himself, to show that he was hateful to both heaven and earth.

(Hil. Quæst. V. et N. Test. q. 94.) Since the Chief Priests were employed about the murder of the Lord from the morning to the ninth hour, how is this proved that before the crucifixion Judas returned them the money he had received, and said to them in the temple, I have sinned, in that I have betrayed innocent blood? Whereas it is manifest that the Chief Priests and Elders were never in the temple before the Lord's crucifixion, seeing that when He was hanging on the Cross they were there to insult Him. Nor indeed can this be proved hence, because it is related before the Lord's Passion, for many things which were manifestly done before, are related after, that, and the reverse. It might have been done after the ninth hour, when Judas, seeing the Saviour dead and the veil of the temple rent, the earthquake, the bursting of the rocks, and the elements terrified, was seized with fear and sorrow thereupon. But after the ninth hour the Chief Priests and Elders were occupied, as I suppose, in the celebration of the Passover; and on the Sabbath, the Law would not have allowed him to bring money. Therefore it is to me as yet unproved on what day or at what time Judas ended his life by hanging.

Then the despair is set forth. For one in despair cares nothing for temporal goods; and so this man acts, because "casting down the pieces of silver in the temple he departed" (he had no care for the money) "and went and hanged himself with …

Secondly, He became his own executioner; He hanged himself; he was suffocated with grief, so Dr. Hammond: but Dr. Whitby is clear that our translation is right. Judas had a sight and sense of sin, but no apprehension of the mercy of God in Christ, and so he pined away in his iniquity.

And he cast down the pieces of silver in the temple,....

The opening of this chapter describes the delivery of our Lord Jesus Christ into the hands of the Gentiles. The chief priests and elders of the Jews led him away to Pontius Pilate, the Roman governor. We may see in this incident the finger of God: it was ordered by his providence that Gentiles as well as Jews should be concerned in the murder of Christ; it was ordered by his providence that the priests should publicly confess that the “scepter had departed from Judah.”

How is this to be explained? Perhaps he flung the money in after them. But thus were fulfilled the words of the prophet--"I cast them to the potter in the house of the Lord" (Zec 11:13). and departed, and went and hanged himself--For the details, see on Ac 1:18.

The opening of this chapter describes the delivery of our Lord Jesus Christ into the hands of the Gentiles. The chief priests and elders of the Jews led him away to Pontius Pilate, the Roman governor. We may see in this incident the finger of God: it was ordered by his providence that Gentiles as well as Jews should be concerned in the murder of Christ; it was ordered by his providence that the priests should publicly confess that the “scepter had departed from Judah.” They were unable to put anyone to death without going to the Romans: the words of Jacob were therefore fulfilled. The Messiah, Shiloh had indeed come ( Genesis 49:10 ). The subject that principally occupies the verses we have read is the melancholy end of the false apostle, Judas Iscariot. It is a subject full of instruction: let us mark well what it contains. We see in the end of Judas a plain proof of our Lord’s innocence of every charge laid against him. If there was any living witness who could give evidence against our Lord Jesus Christ, Judas Iscariot was the man. A chosen apostle of Jesus, a constant companion in all his journeyings, a hearer of all his teaching, both in public and private—he must have known well if our Lord had done any wrong, either in word or deed. A deserter from our Lord’s company, a betrayer of him into the hands of his enemies, it was his interest for his own character’s sake, to prove Jesus guilty. It would extenuate and excuse his own conduct if he could make out that his former Master was an offender and an impostor. Why then did not Judas Iscariot not come forward? Why did he not stand forth before the Jewish council and specify his charges, if he had any to make? Why did he not venture to accompany the chief priests to Pilate, and prove to the Romans that Jesus was a malefactor? There is but one answer to these questions.

In the temple - Ναος signifies, properly, the temple itself, into which none but the priests were permitted to enter; therefore εν τῳ ναῳ must signify, near the temple, by the temple door, where the boxes stood to receive the free-will offerings of the people, for the support and repairs of the sacred edifice. See this amply proved by Kypke. Hanged himself - Or was strangled - απηγξατο. Some eminent critics believe that he was only suffocated by excessive grief, and thus they think the account here given will agree with that in Act 1:18. Mr. Wakefield supports this meaning of the word with great learning and ingenuity. I have my doubts - the old method of reconciling the two accounts appears to me quite plausible - he went and strangled himself, and the rope breaking, he fell down, and by the violence of the fall his body was bursted, and his bowels gushed out. I have thought proper, on a matter of such difficulty, to use the word strangled, as possessing a middle meaning between choking or suffocation by excessive grief, and hanging, as an act of suicide. See the note on Mat 10:4. Dr. Lightfoot is of opinion that the devil caught him up into the air, strangled him, and threw him down on the ground with violence, so that his body was burst, and his guts shed out! This was an ancient tradition.
