But this he did not say of himself; but, being high priest that year, prophesied that Jesus was going to die for the nation;

And this he said not of himself, but being chief priest of that year, he did prophesy that Jesus was about to die for the nation,

It was not as a mere man that he thus spoke. But being High Priest that year he was inspired to declare that Jesus was to die for the nation,

He did not say this of himself, but being the high priest that year he said, as a prophet, that Jesus would be put to death for the nation;

Yet he did not say this from himself, but since he was the high priest that year, he prophesied that Jesus would die for the nation.

Now he did not say this of his own accord; but, as high priest that year, he prophesied that Jesus was to die for the nation –

Now he spoke this, not of himself. When the Evangelist says that Caiaphas did not speak this of himself, he does not mean that Caiaphas -- like one who was mad, or out of his senses -- uttered what he did not understand; for he spoke what was his own opinion. But the Evangelist means that a higher impulse guided his tongue, because God intended that he should make known, by his mouth, something higher than what occurred to his mind. Caiaphas, therefore, might be said, at that time, to have two tongues; for he vomited out the wicked and cruel design of putting Christ to death, which he had conceived in his mind; but God turned his tongue to a different purpose, so that, under ambiguous words, he likewise uttered a prediction. God intended that the heavenly oracle should proceed from the high priest's seat, that the Jews might have less excuse. For, though not one person in the whole assembly had his conscience moved, yet they afterwards perceived that their insensibility was not entitled to forgiveness. Nor did the wickedness of Caiaphas prevent his tongue from being the organ of the Holy Spirit, for God looked at the priesthood which he had instituted rather than at the person of the man. And this was the reason which I glanced at, that a voice uttered from a lofty place might be more distinctly heard, and might have greater reverence and authority. In the same manner, God intended to bless his people by the mouth of Balaam, on whom he had bestowed the spirit of prophecy. But it is highly ridiculous in the Papists to infer from this that we ought to reckon as an oracle whatever the Roman high priest may think fit to pronounce. First, granting what is false, that every man who is a high priest is also a prophet, still they will be under the necessity of proving that the Roman high priest is appointed by the command of God; for the priesthood was abolished by the coming of one man, who is Christ, and we no where read that it was afterwards enjoined by God that any one man should be the ruler of the whole Church. Granting to them, in the second place, that the power and title of high priest was conveyed to the Bishop of Rome, we must see of what advantage it was to the priests that they accepted the prediction of Caiaphas In order to concur in his opinion, they conspire to put Christ to death. But far from us be that kind of obedience which drives us to horrid apostacy by denying the Son of God. With the same voice Caiaphas blasphemes and also prophesies. They who follow his suggestion despise the prophecy, and adopt the blasphemy. We ought to guard against the same thing happening to us, if we listen to the Caiaphas of Rome; for otherwise the comparison would be defective. Besides, I ask, Must we conclude that, because Caiaphas once prophesied, every word uttered by the high priest is always a prophecy? But soon afterwards Caiaphas condemned as blasphemy (Matthew 26:65) the most important article of our faith. Hence we conclude, that what the Evangelist now relates was an extraordinary occurrence, and that it would be foolish to adduce it as an example. That Jesus would die. First, the Evangelist shows that the whole of our salvation consists in this, that Christ should assemble us into one; for in this way he reconciles us to the Father, in whom is the fountain of life, (Psalm 36:9.) Hence, also, we infer, that the human race is scattered and estranged from God, until the children of God are assembled under Christ their Head. Thus, the communion of saints is a preparation for eternal life, because all whom Christ does not gather to the Father remain in death, as we shall see again under the seventeenth chapter. For the same reason Paul also teaches that Christ was sent, in order that he might gather together all things which are in heaven and in earth, (Ephesians 1:10.) Wherefore, that we may enjoy the salvation brought by Christ, discord must be removed, and we must be made one with God and with angels, and among ourselves. The cause and pledge of this unity was the death of Christ, by which he drew all things to himself; but we are daily gathered by the Gospel into the fold of Christ.

Not of himself - Though he uttered what proved to be a true prophecy, yet it was accomplished in a way which he did not intend He had a wicked design. He was plotting murder and crime. Yet, wicked as he was, and little as he intended it, God so ordered it that he delivered a most precious truth respecting the atonement. Remark:
1. God may fulfill the words of the wicked in a manner which they do not wish or intend.
2. He may make even their malice and wicked plots the very means of accomplishing his purposes. What they regard as the fulfillment of their plans God may make the fulfillment of his, yet so as directly to overthrow their designs, and prostrate them in ruin.
3. Sinners should tremble and be afraid when they lay plans against God, or seek to do unjustly to others.
Being high priest that year - It is not to be supposed that Caiaphas was a true prophet, or was conscious of the meaning which John has affixed to his words; but his words express the truth about the atonement of Jesus, and John records it as a remarkable circumstance that the high priest of the nation should unwittingly deliver a sentiment which turned out to be the truth about the death of Jesus. Great importance was attached to the opinion of the high priest by the Jews, because it was by him that the judgment by Urim and Thummim was formerly declared in cases of importance and difficulty, Numbers 27:21. It is not certain or probable that the high priest ever was endowed with the gift of prophecy; but he sustained a high office, the authority of his name was great, and it was thence remarkable that he uttered a declaration which the result showed to be true, though not in the sense that he intended.
He prophesied - He uttered words which proved to be prophetic; or he expressed at that time a sentiment which turned out to be true. It does not mean that he was inspired, or that he deserved to be ranked among the true prophets; but his words were such that they accurately expressed a future event. The word "prophecy" is to be taken here not in the strict sense, but in a sense which is not uncommon in the sacred writers. Acts 21:9; "and the same man had four daughters, virgins, which did prophesy." See the Romans 12:6 note; 1-Corinthians 14:1 note; compare Matthew 26:68; Luke 22:64.
That Jesus should die - Die in the place of men, or as an atonement for sinners. This is evidently the meaning which John attaches to the words.
For that nation - For the Jews. As a sacrifice for their sins. In no other sense whatever could it be said that he died for them. His death, so far from saving them in the sense in which the high priest understood it, was the very occasion of their destruction. They invoked the vengeance of God when they said, "His blood be on us and on our children" Matthew 27:25, and all these calamities came upon them because they would not come to him and be saved - that is, because they rejected him and put him to death, Matthew 23:37-39.

This spake he not of himself - Wicked and worthless as he was, God so guided his tongue that, contrary to his intention, he pronounced a prophecy of the death of Jesus Christ.
I have already remarked that the doctrine of a vicarious atonement had gained, long before this time, universal credit in the world. Words similar to these of Caiaphas are, by the prince of all the Roman poets, put in the mouth of Neptune, when promising Venus that the fleet of Aeneas should be preserved, and his whole crew should be saved, one only excepted, whose death he speaks of in these remarkable words: -
"Unum pro multis dabitar caput."
"One life shall fall, that many may be saved."
Which victim the poet informs us was Palinurus, the pilot of Aeneas's own ship, who was precipitated into the deep by a Divine influence. See Virg. Aen. v. l. 815, etc.
There was no necessity for the poet to have introduced this account. It was no historic fact, nor indeed does it tend to decorate the poem. It even pains the reader's mind; for, after suffering so much in the sufferings of the pious hero and his crew, he is at once relieved by the interposition of a god, who promises to allay the storm, disperse the clouds, preserve the fleet, and the lives of the men; but, - one must perish! The reader is again distressed, and the book ominously closes with the death of the generous Palinurus, who strove to the last to be faithful to his trust, and to preserve the life of his master and his friend. Why then did the poet introduce this? Merely, as it appears to me, to have the opportunity of showing in a few words his religious creed, on one of the most important doctrines in the world; and which the sacrificial system of Jews and Gentiles proves that all the nations of the earth credited.
As Caiaphas was high priest, his opinion was of most weight with the council; therefore God put these words in his mouth rather than into the mouth of any other of its members. It was a maxim among the Jews that no prophet ever knew the purport of his own prophecy, Moses and Isaiah excepted. They were in general organs by which God chose to speak.

(8) And this spake he not of himself: but being high priest that year, he prophesied that Jesus should die for that nation;
(8) Christ sometimes turns the tongues, even of the wicked, so that even in cursing they bless.

And this spake he not of himself,.... Not of his own devising and dictating, but by the Spirit of God; as a wicked man sometimes may, and as Balaam did; the Spirit of God dictated the words unto him, and put them into his mouth; nor did he use them in the sense, in which the Holy Ghost designed them:
but being high priest that year; by his office he was the oracle of God, and was so esteemed by the people, and therefore a proper person to be made use of in this way; and especially being high priest that year, in which the priesthood was to be changed, and vision and prophecy to be sealed up:
he prophesied; though he did not know he did, as did Pharaoh, Exodus 10:28, and the people of the Jews, Matthew 27:25.
That Jesus should die for that nation; these words, with what follows in the next verse, are the words of the evangelist, interpreting the prophecy of Caiaphas, according to the sense of the Holy Ghost that Jesus should die, which was contrary to a notion the Jews had imbibed, concerning the Messiah; see John 12:34. But Jesus the true Messiah must die; this was determined in the counsel of God, agreed to by Christ in the covenant of grace, foretold by the prophets from the beginning of the world, typified by sacrifices and other things, under the former dispensation, predicted by Christ himself, and accordingly came to pass; and upon the above accounts was necessary, as well as for the salvation of his people, who otherwise must have perished; and yet was free and voluntary in him, and a strong expression, and a demonstrative proof of his love to them: and not only this prophecy declared, that Jesus should die, but that he should die for that nation, for the nation of the Jews; not for every individual in it, for all of them were not saved by him; some received him not; they rejected him as the Messiah, Saviour, and Redeemer, and died in their sins; but for all the elect of God among them, the sheep of the house of Israel, to whom he was sent, and whom he came to seek and save; and whom he blessed, by turning them away from their iniquities, and by taking away their iniquities from them: and moreover, this prophecy suggests, that Jesus was to die, not merely as a martyr, to confirm with his blood the doctrine he preached, nor only as an example of courage, meekness, patience, and love, but for, or in the room and stead of his people, as their surety; giving his life a ransom and himself a sacrifice to the justice of God, for them; there by fulfilling the law and satisfying it, and appeasing the wrath of God on their account.

Caiaphas . . . prophesied that Jesus should die for that nation--He meant nothing more than that the way to prevent the apprehended ruin of the nation was to make a sacrifice of the Disturber of their peace. But in giving utterance to this suggestion of political expediency, he was so guided as to give forth a divine prediction of deep significance; and God so ordered it that it should come from the lips of the high priest for that memorable year, the recognized head of God's visible people, whose ancient office, symbolized by the Urim and Thummim, was to decide in the last resort, all vital questions as the oracle of the divine will.

This spake he not of himself. He thought he spoke of himself, but without his knowledge, God used the lips of the high priest for a prophecy. It "did behoove Jesus to die," in order to save, not that nation only, but that he should gather together in one the children of God.
