Revelation 16:5 WEB

³  The second angel poured out his bowl into the sea, and it became blood as of a dead man. Every living thing in the sea died.

⁴  The third poured out his bowl into the rivers and springs of water, and they became blood.

⁵  I heard the angel of the waters saying, 'You are righteous, who are and who were, you Holy One, because you have judged these things.

⁶  For they poured out the blood of the saints and the prophets, and you have given them blood to drink. They deserve this.'

⁷  I heard the altar saying, 'Yes, Lord God, the Almighty, true and righteous are your judgments.'
