Matthew Henry Presbyterian @wholebiblehenry

Here, in the close of this discourse, I. Christ appoints his disciples to observe the signs of the times, which they might judge by, if they had an eye to the foregoing directions, with as much certainty and assurance as they could judge of the approach of summer by the budding forth of the trees, Luk 21:29-31.

This generation--not "this nation," as some interpret it, which, though admissible in itself, seems very unnatural here. It is rather as in Luk 9:27.

This generation - This race of men; but see on Mat 24:34 (note), and Mar 13:30 (note).
