Matthew Poole and continuators on Revelation 9:2

2 And he opened the bottomless [illegible: 1 letter]t , and there arose a smoke out of the pit, as the smoke of a great fornace ; and the sun and the air were darkned, by reason of the smoke of the pit .

He was a means of Hell's breaking loose, by loosing Satan.

I had rather interpret this generally of the great Influence upon the World, that the Devil, being loosed, had, in filling the World with Ignorance, Error, and Wickedness, (for which this and the following Age are infamous in all Histories) and then particularly of the Errors this time abounded with.

This Influence of the Devil darkned the Sun of the Gospel, and the whole Church of that Age with Ignorance, Error, and abominable Superstition in the Worship of God, attended with the lewdness and Debauchery of Men in their Lives, which usually go altogether.
