And the name of the star is called {8} Wormwood: and the third part of the waters became wormwood; and many men died of the waters, because they were made bitter.

(8) This is spoken by metaphor of a commonly known bitter herb: unless perhaps a man following those that note the derivation of words would rather explain it as an adjective for that which cannot be drunk because of its bitterness, causing the liquid it is made into to be more bitter than any man can drink.

People's New Testament

8:11 The name of the star is called Wormwood. That is, it is bitterness, because it shall fill the world with bitter sorrow. A star is a symbol of a great leader. Such a star as this, a blazing meteor, is a symbol of a leader who suddenly appears, rapidly does an awfully baleful work, and then disappears.

And the third part of the waters became wormwood. In some way the rivers will be the scenes of his malign influence. They shall become bitterness and shall be scenes of death.

Wesley's Notes

8:11 And the name of the star is called Wormwood - The unparalleled bitterness both of Arius himself and of his followers show the exact propriety of his title. And the third part of the waters became wormwood - A very considerable part of Afric was infected with the same bitter doctrine and Spirit. And many men (though not a third part of them) died - By the cruelty of the Arians.

Jamieson-Fausset-Brown Bible Commentary

11. The symbolizers interpret the star fallen from heaven as a chief minister (Arius, according to Bullinger, Bengel, and others; or some future false teacher, if, as is more likely, the event be still future) falling from his high place in the Church, and instead of shining with heavenly light as a star, becoming a torch lit with earthly fire and smouldering with smoke. And "wormwood," though medicinal in some cases, if used as ordinary water would not only be disagreeable to the taste, but also fatal to life: so "heretical wormwood changes the sweet Siloas of Scripture into deadly Marahs" [Wordsworth]. Contrast the converse change of bitter Marah water into sweet, Ex 15:23. Alford gives as an illustration in a physical point of view, the conversion of water into firewater or ardent spirits, which may yet go on to destroy even as many as a third of the ungodly in the latter days.

Matthew Henry's Concise Commentary

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.

Matthew Henry's Whole Bible Commentary

Verses 7-13

Observe, I. The first angel sounded the first trumpet, and the events which followed were very dismal: There followed hail and fire mingled with blood, etc., v. 7. There was a terrible storm; but whether it is to be understood of a storm of heresies, a mixture of monstrous errors falling on the church (for in that age Arianism prevailed), or a storm or tempest of war falling on the civil state, expositors are not agreed. Mr. Mede takes it to be meant of the Gothic inundation that broke in upon the empire in the year 395, the same year that Theodosius died, when the northern nations, under Alaricus, king of the Goths, broke in upon the western parts of the empire. However, here we observe, 1. It was a very terrible storm-fire, and hail, and blood: a strange mixture! 2. The limitation of it: it fell on the third part of the trees, and on the third part of the grass, and blasted and burnt it up; that is, say some, upon the third part of the clergy and the third part of the laity; or, as others who take it to fall upon the civil state, upon the third part of the great men, and upon the third part of the common people, either upon the Roman empire itself, which was a third part of the then known world, or upon a third part of that empire. The most severe calamities have their bounds and limits set them by the great God.

II. The second angel sounded, and the alarm was followed, as in the first, with terrible events: A great mountain burning with fire was cast into the sea; and the third part of the sea became blood, v. 8. By this mountain some understand the leader or leaders of the heretics; others, as Mr. Mede, the city of Rome, which was five times sacked by the Goths and Vandals, within the compass of 137 years; first by Alaricus, in the year 410, with great slaughter and cruelty. In these calamities, a third part of the people (called here the sea or collection of waters) were destroyed: here was still a limitation to the third part, for in the midst of judgment God remembers mercy. This storm fell heavy upon the maritime and merchandizing cities and countries of the Roman empire.

III. The third angel sounded, and the alarm had the like effects as before: There fell a great star from heaven, etc., v. 10. Some take this to be a political star, some eminent governor, and they apply it to Augustulus, who was forced to resign the empire to Odoacer, in the year 480. Others take it to be an ecclesiastical star, some eminent person in the church, compared to a burning lamp, and they fix it upon Pelagius, who proved about this time a falling star, and greatly corrupted the churches of Christ. Observe, 1. Where this star fell: Upon a third part of the rivers, and upon the fountains of waters. 2. What effect it had upon them; it turned those springs and streams into wormwood, made them very bitter, that men were poisoned by them; either the laws, which are springs of civil liberty, and property, and safety, were poisoned by arbitrary power, or the doctrines of the gospel, the springs of spiritual life, refreshment, and vigour to the souls of men, were so corrupted and embittered by a mixture of dangerous errors that the souls of men found their ruin where they sought for their refreshment.

IV. The fourth angel sounded, and the alarm was followed with further calamities. Observe, 1. The nature of this calamity; it was darkness; it fell therefore upon the great luminaries of the heaven, that give light to the world-the sun, and the moon, and the stars, either the guides and governors of the church, or of the state, who are placed in higher orbs than the people, and are to dispense light and benign influences to them. 2. The limitation: it was confined to a third part of these luminaries; there was some light both of the sun by day, and of the moon and stars by night, but it was only a third part of what they had before. Without determining what is matter of controversy in these points among learned men, we rather choose to make these plain and practical remarks:-(1.) Where the gospel comes to a people, and is but coldly received, and has not its proper effects upon their hearts and lives, it is usually followed with dreadful judgments. (2.) God gives warning to men of his judgments before he sends them; he sounds an alarm by the written word, by ministers, by men's own consciences, and by the signs of the times; so that, if a people be surprised, it is their own fault. (3.) The anger of God against a people makes dreadful work among them; it embitters all their comforts, and makes even life itself bitter and burdensome. (4.) God does not in this world stir up all his wrath, but sets bounds to the most terrible judgments. (5.) Corruptions of doctrine and worship in the church are themselves great judgments, and the usual causes and tokens of other judgments coming on a people.

V. Before the other three trumpets are sounded here is solemn warning given to the world how terrible the calamities would be that should follow them, and how miserable those times and places would be on which they fell, v. 13. 1. The messenger was an angel flying in the midst of heaven, as in haste, and coming on an awful errand. 2. The message was a denunciation of further and greater woe and misery than the world had hitherto endured. Here are three woes, to show how much the calamities coming should exceed those that had been already, or to hint how every one of the three succeeding trumpets should introduce its particular and distinct calamity. If less judgments do not take effect, but the church and the world grow worse under them, they must expect greater. God will be known by the judgments that he executes; and he expects, when he comes to punish the world, the inhabitants thereof should tremble before him.
