Primasius of Hadrumetum, on Rev 9:9

“And they had breastplates as breastplates of iron, and the noise of their wings was as the noise of chariots and many horses running to battle.”

“[The noise of their wings was like the sound of chariots] signifies that the few who were in the lead as the horses have now been multiplied in the chariots [that follow]. This suggests either an increase in the diversity of new opinions or the increase in the number of those who have been led astray. Moreover, they rush into battle because the preachers of error rebel against the truth and fight against unity. The apostle described such persons in a similar fashion, "As Jannes and Jambres opposed Moses, so these men also oppose the truth, men of corrupt mind and counterfeit faith," and following. … [That they had power in their tails] reminds us of what Isaiah wrote, "The elder and the honored man is the head, and the prophet who teaches falsehood is the tail, and those who bless my people will lead them astray, and those who are blessed have fallen." It is clear from this that these persons wish to rule that which every saint and teacher of the truth desires at all costs to avoid, namely, the glory of the world and the error of a destructive preaching. That they have power in their tails for five months indicates again the present life where falsehood can be strong and can either capture the useless or torment the spiritual for a short period of time.”
