For in my jealousy, and in the fire of my wrath, have I spoken,.... Not against his people Israel, but against Gog, who had thought evil against them, and now was about to put it in practice; and therefore in zeal for his own glory, and for the good of his people, and in indignation against his and their enemies, he declares, resolves, and determines:

surely in that day there shall be a great shaking in the land of Israel; not a consternation among the people of Israel frightened at the armies of Gog, and the terrible appearance they shall make, and the devastations they threaten; but in Gog himself, and his army, through the wrath of God upon them, and the vengeance he will take of them in the land of Israel, they will enter upon to destroy; not but that there may be some dread in the minds of the Jews upon the appearance of so formidable an army in their land: this shaking, according to Jarchi, will be by thunder and lightning. Kimchi understands it of an earthquake, in a literal sense, and compares with it Zechariah 14:4, see also Revelation 16:18, which speaks of an earthquake that will be about this time.

For in my jealousy and in the fire of my wrath have I spoken, Surely in that day there shall be a great shaking in the land of Israel;

38:19 For - For my own people, and for mine own glory. Have I spoken - Against mine enemies Gog, and all his herd. A great shaking - A great disturbance and tumult, like an earthquake.

19. great shaking-an earthquake: physical agitations after accompanying social and moral revolutions. Foretold also in Joe 3:16; (compare Hag 2:6, 7; Mt 24:7, 29; Re 16:18).

38:14-23 The enemy should make a formidable descent upon the land of Israel. When Israel dwell safely under the Divine protection, shalt not thou be made to know it by finding that endeavours to destroy them are made in vain? Promises of security are treasured up in the word of God, against the troubles and dangers the church may be brought into in the latter days. In the destruction of sinners, God makes it appear that he is a great and holy God. We should desire and pray daily. Father, glorify thine own name.
