Revelation 9:9 Revelation 9:9 And they had breastplates, as it were breastplates of iron; and the sound of their wings was as the sound of chariots of many horses running to battle. By their breast-plates, as it were of iron, we may understand their external defence for self-preservations, both of their persons and privileges; that is, the popish canons, their holy orders, and ecclesiastical laws, whereby those locusts were protected, as from the violence of the common people, so from the power of kings and their laws, and the sound of their wings was as the sound of chariots, of many horses running to battle. Wings signify their readiness to the work of their ministry. \ See the Exposition of Wings there- See KNOLLYS: Revelation 4:8 By the resemblance of chariots and horses, we may understand what a terror they were to all sorts of people that would oppose them; as the true Church of God is said to be terrible as an army with banners, \ so those locusts are terrible, as chariots and many horses running to battle.. Revelation 13:4 Who is like unto the Beast, who is able to make war with him?
