Matthew 23:36

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.

For he who having seen many sinning yet remains uncorrected, but rather does the same or worse, is obnoxious to heavier punishment.

(ord.) He means not only those there present, but the whole generation before and after, for all were one city and one body of the Devil.

Then, because He was searching their temper of mind, which is to the more part obscure, He doth, from those things also which they were about to perpetrate, which would be manifest to all, establish His words. For, because He had said, "Wherefore ye be witnesses unto yourselves that ye are the children of them which killed the prophets," making it evident, that of their affinity in wickedness He is speaking, and that it was a pretense to say, "We should not have been partakers with them," He added, "Fill ye up therefore the measure of your fathers," not commanding, but declaring beforehand, what was to be, that is, His own murder. Therefore, having brought in their refutation, and having shown that they were pretenses which they said in their own defense, as, for instance, "We would not have been partakers with them," (for they who refrain not from the Lord, how should they have refrained from the servants), He makes after this His language more condemnatory, calling them "serpents, and generation of vipers," and saying, "How shall ye escape the damnation of hell," at once perpetrating such things, and denying them, and dissembling your purpose? Then rebuking them more exceedingly from another cause also, He Saith, "I will send unto you prophets, and wise men, and scribes, and some of them shall ye kill and crucify, and some of them shall ye scourge in your synagogues." For that they should not say, "Though we crucified the Lord, yet from the servants we should have refrained, if we had been then;" "Behold," He saith, "I send servants also to you, prophets likewise themselves, and neither will ye spare them." But these things He saith, showing that it was nothing strange, that He should be murdered by those sons, being both murderous and deceitful, and having much guile, and surpassing their fathers in their outrages. And besides what hath been said, He shows them to be also exceedingly vainglorious. For when they say, "If we had been in the days of our fathers, we should not have been partakers with them," they spake out of vainglory, and were practising virtue in words only, but in their works doing the contrary. Ye serpents, ye generation of vipers, that is, wicked sons of wicked men, and more wicked than those who begat them. For He showeth that they are committing greater crimes, both by their committing them after those others, and by their doing much more grievous things than they, and this, while positively affirming that they never would have fallen into the same. For they add that which is both the end and the crown of their evil deeds. For the others slew them that came to the vineyard, but these, both the son, and them that were bidding them to the wedding. But these things He saith, to separate them off from the affinity to Abraham, and to show that they had no advantage from thence, unless they followed his works; wherefore also He adds, "How can ye flee from the damnation of hell," when following them that have committed such acts? And here He recalls to their remembrance John's accusation, for he too called them by this name, and reminded them of the judgment to come. Then, because they are nothing alarmed by judgment and hell, by reason of their not believing them, and because the thing is future, He awes them by the things present, and saith, "Wherefore, behold, I send unto you prophets and scribes: and some of them shall ye kill and crucify, and scourge; that upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel, unto the blood of Zacharias the son of Barschias, whom ye slew between the temple and the altar. Verily I say unto you, that all these things shall come upon this generation." See by how many things He has warned them. He said, Ye condemn your fathers, in that ye say, "We would not have been partakers with them;" and this is no little thing to shame them. He said, While ye condemn them, ye do worse things, even ye yourselves; and this is sufficient to cover

The rule of the Scriptures is only to know two generations, one of good the other of bad. Of the generation of the good it is said, The generation of the righteous shall be blessed. (Ps. 112:2.) And of the bad it is said in the present passage, Generation of vipers. These then, because they did against the Apostles like things as Cain and Joas, are described as of one generation.
