Revelation 16:7

“And I heard another out of the altar say, etc.] That is, another angel that came out of the altar; (see <661418>Revelation 14:18) and who represents the souls under the altar, whose blood had been shed by the above persons; compare with this (<660609>Revelation 6:9) though, there, such whose blood had been shed by Rome Pagan are described; the Ethiopic version calls this angel as before, “the angel of the fountains of water”; and the Alexandrian copy, and Syriac and Arabic versions, read, “I heard the altar saying”: as follows, even so, Lord God Almighty, true and righteous are thy judgments; the same as in (<661503>Revelation 15:3 19:2).

“And I heard another - Evidently another angel, though this is not specified. Out of the altar - Either the angel of the altar - that is, who presided over the altar (Prof. Stuart), or an angel whose voice seemed to come from the altar. The sense is essentially the same. The writer seemed to hear a voice coming from the altar responding to what had just been said in regard to the judgment of God, or to his righteousness in bringing the judgment upon people, Revelation 16:5. This was evidently the voice of someone who was interested in what was occurring, or to whom these things particularly pertained; that is, one who was particularly connected with the martyrs referred to, whose blood was…”

“Yea - Answering the angel of the waters, and affirming of God's judgments in general, what he had said of one particular judgment. Revelation 16:8”

“16:7 I heard a voice from the altar: The antiphonal response to the angel’s proclamation (16:5-6) affirms God’s authority and justice. This doxology in the midst of judgment reminds persecuted Christians that God truly cares about his suffering servants and fulfills his own purpose in everything.”
