“And to take away all excuse from them that they might not say, Because you sent them to the Gentiles thereat were we offended, He foretels that His disciples should be sent to them, and it is of their punishment that He adds, Verily I say unto you, all these things shall come upon this generation.”
“Otherwise; Because He delayed the punishment of hell which He had threatened them with, He pronounces against them threats of present evil, saying, All these things shall come upon this generation.”

“Behold, I. In this part he sets forth their cruelty, and adds the temporal punishment. And first he does the first; second he adds the punishment. And first he sets forth the benefit; second the fault; third the magnitude of the punishment. Hence he says, "Behold, I send to you prophets, and wise men and scribes," and so on. And it can be referred to that which immediately follows, or to that whole which follows. If to the whole, then it has a plainer sense. Thus I say that you are about to fill up, and that you are serpents, and so on. Hence, "I send to you prophets, and wise men, and scribes," and some of them you will kill, because you are such as have been accustomed to kill. Or otherwise, so that it is referred to the whole. The Lord wills that judgment be not only just, but that it appear just, so that others may take examples from it. Hence if someone has a good purpose, the Lord rewards him for the good purpose, and thence gives him the will to carry out a good work; so on the contrary, when someone has an evil purpose, and is full of evil will, according to what is said in Hosea 2:6: "I will hedge up your way with thorns," he stirs up the wrath of God, and from the wrath of God it comes about that his malice is made manifest. Therefore, "I send to you prophets, and wise men, and scribes"; and you will kill them. And he says "behold," because it is at hand, because he sent the apostles; hence Acts 1:8: "and you shall be my witnesses in Jerusalem, and in all Judea and Samaria, and even to the end of the earth." But note that in this, that he says "I send to you prophets, and wise men, and scribes," he signifies the various gifts of the Holy Spirit. To one is given the gift of wisdom, to another kinds of tongues, and so on. 1 Corinthians 12:10. The apostles had all these gifts. They had the gift of prophecy in telling future things; Joel 2:28: "I will pour out of my spirit upon all peoples, and your sons and your daughters shall prophesy." Likewise wisdom, because they knew all things; Luke 21:15: "I will give you a mouth and wisdom, which all your adversaries will not be able to resist and contradict." Likewise they were scribes, because they had understanding of Scripture; Luke 24:45: "he opened their understanding, that they might understand the Scriptures." And why does he foretell this? So that the disciples, thinking on what they have heard, might more easily endure it. Likewise, to convict their malice, because just as their fathers killed the prophets, so these would kill the apostles; hence "some of them you will kill," as is found in Acts 12:2, because Herod killed James the brother of John with the sword, seeing that it pleased the Jews. Others were crucified; hence also "you will crucify." For this was the vilest death, therefore they killed Christ by this death, according to that saying of Wisdom 2:20: "let us condemn him to a most shameful death." And "you will scourge." Acts 5:40 says that, having beaten them, they charged them that they should not speak at all in the name of Jesus. And "you will persecute." This is evident from how they persecuted Paul. And above, chapter 10:23: "if they persecute you in one city, flee into another." Further, the punishment is set forth, which, because it seemed grave, he therefore confirms: "Amen I say to you, all these things shall come upon this generation." He says: that upon you may come all the righteous blood, from the blood of Abel the just even unto the blood of Zechariah the son of Barachiah. Who this Abel is, is known, because he was killed by Cain his brother. But who this Zechariah was is not established. It is read that there were three Zechariahs. One the son of Barachiah, who was the eleventh among the prophets. But it cannot be understood of this one, because there was not yet an altar. Another was the father of John, and whose son he was is not found; but Chrysostom says that he was killed on account of Christ, because in the temple there was a place of the virgins, and when the Virgin Mary was sitting in the place of the virgins, the Jews wanted to expel her from the place; which Zechariah forbade, defending her, and on account of this he was killed. Another is said to be the son of Jehoiada, whom Joash killed in the court of the temple, therefore "between the temple and the altar"; hence the place agrees, but the name is discordant. But yet Jerome says that it is interpreted "blessed of the Lord," and the holiness of his father Jehoiada the priest is thereby designated. And he says that he himself saw the Gospel of the Nazarenes, and there it was contained, "the son of Jehoiada." But why it begins with this Zechariah can be a question of the letter. The reason, however, seems to be that although the preceding [killings] were more frequent, yet these were the ones found in Scripture. Or otherwise, that Abel was a shepherd, Jehoiada a priest; therefore by these two are signified the laity and the clergy. Hence every punishment for the killing of men shall come upon you. Or otherwise, because some are active, some contemplative; hence both are signified by these two. But "amen I say to you, that all these things shall come upon this generation." But how can it be that all these things come upon this generation? Is one punished for another? Ezekiel 18:20: "the son shall not bear the iniquity of the father." How then upon this generation? Jerome solves this, [saying] that it is customary in Scripture that the whole generation of the good is taken for one generation, concerning which in Psalm 111:2: "the generation of the upright shall be blessed." Concerning the generation of the wicked, above, 12:39: "an evil generation seeks a sign." Chrysostom says thus: some sin, but God does not immediately avenge; hence in Psalm 7:12: "does he grow angry every day?" But some, when they sin, are never corrected, but change for the worse; 2 Timothy 3:13: "but evil men and seducers shall grow worse and worse"; and then the Lord waits until their malice is completed. Hence these, in whom the malice will be completed, bear the weight of the whole as regards the temporal punishment, yet as regards the eternal punishment, each bears his own. Hence it will be so great that it will seem that they suffer for all; hence Exodus 32:34, it is said that this sin is reserved until the day of vengeance. Just as there was a fullness of good things for those who believe in Christ, so a fullness of evils for those who killed Christ; therefore he says, "all these things shall come upon this generation." But what is this punishment? The destruction of the city of Jerusalem. And since he intends to speak of the destruction of the city, therefore he turns himself to the city, saying, "Jerusalem, Jerusalem." And first he sets forth the offense; second he commemorates the benefits; third he foretells the punishment. The second is there: "how often would I have gathered your children ... and you would not?" The third is there: "behold, your house shall be left to you desolate." He says therefore, "Jerusalem, Jerusalem"; and this doubling designates the affection of one who pities; hence it is said in Luke 19:41, that seeing the city he wept over it. "You who kill the prophets"; Acts 7:52: "which of the prophets have not your fathers persecuted?" And he says "you who kill," not "you who have killed," because they were still persevering in malice. This is that Jerusalem, of which it is said in Ezekiel 5:6: "this is Jerusalem, I have set her in the midst of the nations, and the countries around her, and she has despised my judgments." They could excuse themselves: "we had no one to tell us"; therefore he says, "and you stone those who are sent to you"; hence "I sent prophets and many helps, and you did not recognize [them]." "How often would I have gathered your children together, as a hen gathers her chicks under her wings, and you would not?" In this is designated the perpetuity of his divinity, according to what he himself says, John 8:58: "before Abraham was made, I am." Hence Christ himself sent prophets, patriarchs, and angels. Whenever he sent, he willed to gather, and so on. Those are gathered who are converted to the Lord, because in him sinners are united; those are scattered who are separated from unity. Hence, "I would have gathered [you] as a hen gathers her chicks under her wings." It is said that there is no animal so compassionate to its young as the hen. The hen defends [them] from the kite, and exposes her life for them, and gathers them under her wings. Thus Christ has compassion on us: "surely he himself bore our infirmities," Isaiah 53:4. Likewise he exposed himself to the kite, that is, the Devil; Deuteronomy 31:27: "while I am yet living and going in with you, you have always acted contentiously against the Lord." But against this: the Lord willed, and these did not will: therefore their evil will prevailed over the will of God. Hence it must be said: as often as I willed, I did it, but with you unwilling, I did it when I did it; hence your will hindered it, so that I did not do it. Or, that he sent prophets was a sign that he willed to gather [you], and you were unwilling. Then follows the punishment: "behold, your house shall be left to you desolate." The whole people was honored on account of Jerusalem, and Jerusalem on account of the temple; therefore it is said, "your house shall be left," that is, the temple, or the dwelling; Psalm 68:26: "let their habitation be made desolate." Or the house is called desolate when it lacks its proper inhabitant; Psalm 10:5: "the Lord is in his holy temple." Hence it is said "to leave" with respect to the indwelling; therefore, "you shall not see me henceforth," etc., because I was with you through the power of my divinity, and afterward I was [with you] bodily, but I will withdraw from you. But now "your house shall be left to you desolate, and you shall not see me henceforth," neither bodily, namely after the Passion, nor spiritually. But is this true, that none of the Jews saw him, since nevertheless many were converted to him? Therefore he says, "until you say: blessed is he who comes in the name of the Lord," because when you shall confess [him], then you will see through faith. Or otherwise, he secretly designates the second coming: they saw him in the body, but they did not have this seeing until the second coming, in which you will be able to say, and you will recognize, that I am he who is blessed who comes in the name of the Lord.”

“Verily I say unto you,.... An usual form of introducing something of moment to raise attention to it, and to ascertain the truth of it: all these things shall come upon this generation; all the things which Christ had foretold should come to pass in the present age; as that the apostles and ministers of the word he should send to them, some of them they would kill and crucify, and others they would scourge in their synagogues, or persecute from place to place; and all the horrible murders and bloodshed in any age, committed by that people, would be placed to the account of the men of that generation; and the guilt of them imputed to them, and the punishment due unto them be inflicted on them. And which came to pass, and had its full accomplishment about forty years after this, in the utter destruction of Jerusalem, and the whole nation; so that many now living were personally involved in that temporal ruin, as well as escaped not the damnation of hell, Mat 23:33.”

“Amen, I say to you. More severe punishments were inflicted on these Jews, on account of their more grievous and heinous transgressions; for nothing had been able to recall them from their wickedness. They had the example of their ancestors before their eyes, continually irritating the wrath of God; yet all they had suffered for their crimes, could not incite them to leave their sinful ways; but they proceeded further than their ancestors in impiety, and ought therefore to receive a more severe condemnation. Thus though Lamech had not killed a brother, but had neglected to be more prudent after the exemplary punishment of Cain, he still cried out: Seven-fold punishment is taken of Cain, but of Lamech seventy times seven. (Genesis iv.) (St. Chrysostom, hom. lxxiii.)”

“Verily I say unto you, All these things shall come upon this generation--As it was only in the last generation of them that "the iniquity of the Amorites was full" (Gen 15:16), and then the abominations of ages were at once completely and awfully avenged, so the iniquity of Israel was allowed to accumulate from age to age till in that generation it came to the full, and the whole collected vengeance of heaven broke at once over its devoted head. In the first French Revolution the same awful principle was exemplified, and Christendom has not done with it yet. Lamentation over Jerusalem and Farewell to the Temple (Mat 23:37-39).”
