(Now the name of the star is Wormwood.) So a third of the waters became wormwood, and many people died from these waters because they were poisoned.

because His judgments are true and righteous. He has judged [convicted and pronounced sentence on] the great prostitute (idolatress) who was corrupting and ruining and poisoning the earth with her adultery (idolatry), and He has imposed the penalty for the blood of His bond-servants on her.”
