Truly, I say to you, this generation will not pass away until all these things take place.
We have here the application of this prophetical sermon; now learn to look forward in a right manner. I. "As to the destruction of Jerusalem, expect it to come very shortly; as when the branch of the fig-tree becomes soft, and the leaves sprout forth, ye expect that summer will come shortly, Mar 13:28. When second causes begin to work, ye expect their effects in their proper order and time.
Commenting on Mark 13:28-37

Of Jerusalem's destruction; for of nothing else had Christ been speaking; and, it is plain, the words are anaphorical, and relate to what goes before: knoweth no man; nay, they that lived to see it, and have spoken of it, are not agreed about the particular day, when it was; much less did they know it beforehand...
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.
