10 And the fifth let what was in his vessel come out on the high seat of the beast; and his kingdom was made dark; and they were biting their tongues for pain. 11 And they said evil things against the God of heaven because of their pain and their wounds; and they were not turned from their evil works.
Matthew Henry's Commentary on Revelation 16:10-11
Commentary on Revelation 16:8-11
(Read Revelation 16:8-11)
The heart of man is so desperately wicked, that the most severe miseries never will bring any to repent, without the special grace of God. Hell itself is filled with blasphemies; and those are ignorant of the history of human nature, of the Bible, and of their own hearts, who do not know that the more men suffer, and the more plainly they see the hand of God in their sufferings, the more furiously they often rage against him. Let sinners now seek repentance from Christ, and the grace of the Holy Spirit, or they will have the anguish and horror of an unhumbled, impenitent, and desperate heart; thus adding to their guilt and misery through all eternity. Darkness is opposed to wisdom and knowledge, and forebodes the confusion and folly of the idolaters and followers of the beast. It is opposed to pleasure and joy, and signifies anguish and vexation of spirit.
