Origen
Catena Aurea · Matthäusevangelium 24
Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh: So likewise ye, when ye shall see all these things, know that it is near, even at the doors. Verily I say unto you, This generation shall not pass, till all these things be fulfilled. Heaven and earth shall pass away, but my words shall not pass away.
The uninstructed refer the words to the destruction of Jerusalem, and suppose them to have been said of that generation which saw Christ’s death, that it should not pass away before the city should be destroyed. But I doubt that they would succeed in thus expounding every word from that, one stone shall not be left upon another, to that, it is even at the door; in some perhaps they would succeed, in others not altogether.
