16:7And I heard the altar saying, "Yes, O Lord God, the Almighty, true and righteous are Thy judgments."
And I heard the altar saying,
John indicates the altar is speaking, but other translations indicate it is another angel or the collective voices of the multitudes underneath the ALTAR (Revelation 6:9-11).
This is the second "witness" to the true and righteous judgments of the ALMIGHTY. The first witness was the "angel of the waters" (verse 5). Thus the Matthew 18:16 requirement to establish the truth is fulfilled.
"Yes, O LORD GOD, THE ALMIGHTY, true and righteous are THY JUDGMENTS."
The phrase "THE ALMIGHTY" is used often in the Revelation. See the list in Revelation 1:8.
Later, in Revelation 19:2, the GREAT MULTITUDE of heaven confirm once more that GOD'S JUDGMENTS are true and righteous. This principle is recognized in the Old Testament in Psalm 19:7-9-14 and Psalm 145:17-21.
Do not think these judgments end when the fourth bowl is poured out. This judgment goes on forever just as the fire on the altar was commanded to burn continually (Leviticus 6:8-13).
