9:3 {5} And there came out of the smoke locusts upon the earth: and unto them was given power, as the scorpions of the earth have power.
(5) A description of the malignant spirits invading the world, taken from their nature, power, form and order. From their nature, for that they are like certain locust, in quickness, subtilty, hurtfulness, number, and such like, in this verse. From their power, for that they are as the scorpions of the earth, of a secret force to hurt: for our battle is not here with flesh and blood, but with powers Eph 6:12 This place of the power of the devils, generally noted in this verse, is particularly declared afterwards in Re 9:4-6.
9:3 There came out of the smoke locusts upon the earth. The destroying locusts symbolize destroying armies. See Na 3:15 Ex 10:12. Observe that they come out of the smoke. To the smoke their origin is due.
Unto them was given power, as the scorpions of the earth have power. Power to hurt is implied, since they are compared to scorpions.
9:3 And out of the smoke - Not out of the bottomless pit, but from the smoke which issued thence. There went forth locusts - A known emblem of a numerous, hostile, hurtful people. Such were the Persians, from whom the Jews, in the sixth century, suffered beyond expression. In the year 540 their academies were stopped, nor were they permitted to have a president for near fifty years. In 589 this affliction ended; but it began long before 540. The prelude of it was about the year 455 and 474: the main storm came on in the reign of Cabades, and lasted from 483 to 532. Toward the beginning of the sixth century, Mar Rab Isaac, president of the academy, was put to death. Hereon followed an insurrection of the Jews, which lasted seven years before they were conquered by the Persians. Some of them were then put to death, but not many; the rest were closely imprisoned. And from this time the nation of the Jews were hated and persecuted by the Persians, till they had well nigh rooted them out. The scorpions of the earth - The most hurtful kind. The scorpions of the air have wings.
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.
