11 The name of the star is Wormwood. A third of the waters became wormwood, and many men died of the water, because it was made bitter. 12 The fourth angel blew his trumpet, and a third of the sun was struck, and a third of the moon, and a third of the stars, so that a third of their light was darkened; a third of the day was kept from shining, and likewise a third of the night. 13 Then I looked, and I heard an eagle crying with a loud voice, as it flew in midheaven, "Woe, woe, woe to those who dwell on the earth, at the blasts of the other trumpets which the three angels are about to blow!"

Commentary on Revelation 8:7-13
(Read Revelation 8:7-13)
The first angel sounded the first trumpet, and there followed hail and fire mingled with blood. A storm of heresies, a mixture of dreadful errors falling on the church, or a tempest of destruction. The second angel sounded, and a great mountain, burning with fire, was cast into the sea; and the third part of the sea became blood. By this mountain some understand leaders of the persecutions; others, Rome sacked by the Goths and Vandals, with great slaughter and cruelty. The third angel sounded, and there fell a star from heaven. Some take this to be an eminent governor; others take it to be some person in power who corrupted the churches of Christ. The doctrines of the gospel, the springs of spiritual life, comfort, and vigour, to the souls of men, are corrupted and made bitter by the mixture of dangerous errors, so that the souls of men find ruin where they sought refreshment. The fourth angel sounded, and darkness fell upon the great lights of heaven, that give light to the world, the sun, and the moon, and the stars. The guides and governors are placed higher than the people, and are to dispense light, and kind influences to them. Where the gospel comes to a people, and has not proper effects on their hearts and lives, it is followed with dreadful judgments. God gives alarm by the written word, by ministers, by men's own consciences, and by the signs of the times; so that if people are surprised, it is their own fault. The anger of God makes all comforts bitter, and even life itself burdensome. But God, in this world, sets bounds to the most terrible judgments. Corruption of doctrine and worship in the church are great judgments, and also are the usual causes and tokens of other judgments coming on a people. Before the other three trumpets were sounded, there was solemn warning how terrible the calamities would be that should follow. If lesser judgments do not take effect the church and the world must expect greater; and when God comes to punish the world, the inhabitants shall tremble before him. Let sinners take warning to flee from the wrath to come; let believers learn to value and to be thankful for their privileges; and let them patiently continue in well doing.
