And I heard another out of the altar say,.... That is, another angel that came out of the altar; see Rev 14:18 and who represents the souls under the altar, whose blood had been shed by the above persons; compare with this Rev 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 Rev 15:3. This angel joins the other, and approves and confirms what he says; applauding the judgements of Christ upon the worshippers of the beast, from the verity of them, being what were threatened, and from the justice of them, being what they deserved.
