6. What takes place when the third bowl is poured out, and what words are heard from an angel and from the altar?

⁶ The third bowl of God’s anger, like the third trumpet blast, has an effect on freshwater sources. “And the third one poured out his bowl into the rivers and the fountains of the waters. And they became blood. And I heard the angel over the waters say: ‘You, the One who is and who was, the loyal One, are righteous, because you have rendered these decisions, because they poured out the blood of holy ones and of prophets, and you have given them blood to drink. They deserve it.’ And I heard the altar say: ‘Yes, Jehovah God, the Almighty, true and righteous are your judicial decisions.’”​—Revelation 16:4-7.

10. What does “the angel over the waters” make known, and what testimony does “the altar” add?

¹⁰ “The angel over the waters,” that is, the angel who pours this bowl into the waters, magnifies Jehovah as the Universal Judge, whose righteous decisions are absolute. Therefore, he says of this judgment: “They deserve it.” Doubtless, the angel personally witnessed much of the bloodshed and cruelty fomented over thousands of years by the false teachings and philosophies of this wicked world. Hence, he knows that Jehovah’s judicial decision is right. Even God’s “altar” speaks out. At Revelation 6:9, 10, the souls of those who were martyred are said to be at the base of that altar. So “the altar” adds powerful testimony as to the justice and righteousness of Jehovah’s decisions.a Certainly, it is fitting that those who have shed and misused so much blood should themselves be force-fed with blood, in symbol of Jehovah’s sentencing them to death.
