“And the name of the star is called Wormwood: and the third part of the waters became wormwood; and many men died of the waters, because they were made bitter.”
King James Version (KJV)
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.
Re 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.
