This generation - Ἡ γενεα αὑτη, This very race of men. It is certain that this word has two meanings in the Scriptures; that given in the text, and that above. Generation signifies a period of a certain number of years, sometimes more, sometimes less. In Deuteronomy 1:35; Deuteronomy 2:14, Moses uses the word to point out a term of thirty-eight years, which was precisely the number in the present case; for Jerusalem was destroyed about thirty-eight years after our Lord delivered this prediction. But as there are other events in this chapter, which certainly look beyond the destruction of Jerusalem, and which were to take place before the Jews should cease to be a distinct people, I should therefore prefer the translation given above. See on Matthew 24:34 (note).

Verily I say unto you, that this generation shall not pass,.... Not the generation of men, in general, or Jews in particular, nor of Christians; but that present generation of men, they should not all go off the stage of life,

till all these things be done; which were now predicted by Christ, concerning the destruction of Jerusalem, the signs of it, and what, should immediately follow upon it; See Gill on Matthew 24:34.

Verily I say unto you, that this generation shall not pass, till all these things be done.

13:30 This generation shall not pass. See PNT Mt 24:34.

13:30 All these things - Relating to the temple and the city.

30. Verily I say unto you, that this generation shall not pass fill all these things be done-or "fulfilled" (Mt 24:34; Lu 21:32). Whether we take this to mean that the whole would be fulfilled within the limits of the generation then current, or, according to a usual way of speaking, that the generation then existing would not pass away without seeing a begun fulfilment of this prediction, the facts entirely correspond. For either the whole was fulfilled in the destruction accomplished by Titus, as many think; or, if we stretch it out, according to others, till the thorough dispersion of the Jews a little later, under Adrian, every requirement of our Lord's words seems to be met.

13:28-37 We have the application of this prophetic sermon. As to the destruction of Jerusalem, expect it to come very shortly. As to the end of the world, do not inquire when it will come, for of that day and that hour knoweth no man. Christ, as God, could not be ignorant of anything; but the Divine wisdom which dwelt in our Saviour, communicated itself to his human soul according to the Divine pleasure. As to both, our duty is to watch and pray. Our Lord Jesus, when he ascended on high, left something for all his servants to do. We ought to be always upon our watch, in expectation of his return. This applies to Christ's coming to us at our death, as well as to the general judgment. We know not whether our Master will come in the days of youth, or middle age, or old age; but, as soon as we are born, we begin to die, and therefore we must expect death. Our great care must be, that, whenever our Lord comes, he may not find us secure, indulging in ease and sloth, mindless of our work and duty. He says to all, Watch, that you may be found in peace, without spot, and blameless.
