Hebreos 12:26

Shook the earth. — Éxodo 19:18; Jueces 5:4. The terrors of Sinai were, moreover, a type of a more terrible revelation of judgment, when not only shall the earth tremble, but the earth and the heaven shall be moved, and all that is transitory and mutable shall pass away.

The words of Hageo 2:6 are taken as a prophecy of this consummation. The reference of the prediction of which this forms part to the first coming of the Messiah is passed over; it is only as bearing upon the last days that the words are quoted here.

Now he hath promised. — This whole time of waiting is included in the “now.” It is as if the words were: “now we have this promise, and are looking for its fulfilment.”

I shake. — Rather (according to the better reading), I will move (or, make to tremble).
