3 The second Angel poured his bowl on the sea: The sea coagulated into blood, and everything in it died. 4 The third Angel poured his bowl on rivers and springs: The waters turned to blood. 5 I heard the Angel of Waters say, Righteous you are, and your judgments are righteous, The Is, The Was, The Holy. 6 They poured out the blood of saints and prophets so you've given them blood to drink - they've gotten what they deserve!
Matthew Henry's Commentary on Revelation 16:3-6
Commentary on Revelation 16:1-7
(Read Revelation 16:1-7)
We are to pray that the will of God may be done on earth as it is done in heaven. Here is a succession of terrible judgments of Providence; and there seems to be an allusion to several of the plagues of Egypt. The sins were alike, and so were the punishments. The vials refer to the seven trumpets, which represented the rise of antichrist; and the fall of the enemies of the church shall bear some resemblance to their rise. All things throughout their earth, their air, their sea, their rivers, their cities, all are condemned to ruin, all accursed for the wickedness of that people. No wonder that angels, who witness or execute the Divine vengeance on the obstinate haters of God, of Christ, and of holiness, praise his justice and truth; and adore his awful judgments, when he brings upon cruel persecutors the tortures they made his saints and prophets suffer.
