And I heard the altar say: ‘Yes, Jehovah God, the Almighty, true and righteous are your judicial decisions.’”​—Revelation 16:4-7.

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.* 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.
