9:1-12 Upon sounding the fifth trumpet, a star fell from heaven to the earth. Having ceased to be a minister of Christ, he who is represented by this star becomes the minister of the devil; and lets loose the powers of hell against the churches of Christ. On the opening of the bottomless pit, there arose a great smoke. The devil carries on his designs by blinding the eyes of men, by putting out light and knowledge, and promoting ignorance and error. Out of this smoke there came a swarm of locusts, emblems of the devil's agents, who promote superstition, idolatry, error, and cruelty. The trees and the grass, the true believers, whether young or more advanced, should be untouched. But a secret poison and infection in the soul, should rob many others of purity, and afterwards of peace. The locusts had no power to hurt those who had the seal of God. God's all-powerful, distinguishing grace will keep his people from total and final apostacy. The power is limited to a short season; but it would be very sharp. In such events the faithful share the common calamity, but from the pestilence of error they might and would be safe. We collect from Scripture, that such errors were to try and prove the Christians, 1Co 11:19. And early writers plainly refer this to the first great host of corrupters who overspread the Christian church.

in, &c.—Greek, "upon their forehead." Thus this fifth trumpet is proved to follow the sealing in Re 7:1-8, under the sixth seal. None of the saints are hurt by these locusts, which is not true of the saints in Mohammed's attack, who is supposed by many to be meant by the locusts; for many true believers fell in the Mohammedan invasions of Christendom.
