And the sixth angel sounded, and I heard a voice from the horns of the golden altar which is before God, one saying to the sixth angel which had the trumpet, Loose the four angels which are bound at the great river Euphrates. And the four angels were loosed, which had been prepared for the hour, and day, and month, and year, that they should kill the third part of men. And the number of the armies of the horsemen was twice ten thousand times ten thousand; I heard the number of them. And thus I saw the horses in the vision, and them that sat on them, having breastplates as of fire, and of hyacinth, and of brimstone. By these three plagues was the third part of men killed, by the fire, and the smoke, and the brimstone, which proceeded out of their mouths. For the power of the horses is in their mouth, and in their tails: for their tails are like unto serpents, and with them they do hurt. And the rest of mankind which were not killed with these plagues repented not of the works of their hands, that they should not worship demons, and the idols of gold, and of silver, and of brass, and of stone, and of wood: which can neither see, nor hear nor walk: and they repented not of their murders, nor of their sorceries, nor of their fornication, nor of their thefts (ix. 13-21). There is much in this Trumpet that is remarkable even while we confine ourselves to the more outward particulars contained in it. Thus we are brought back by it to the thought of those prayers of the saints to which all the Trumpets are a reply, but which have not been mentioned since the blowing of the Trumpets began.[219] Once more we read of _the golden altar which was before God_, in His immediate presence. On that altar the prayers of all the saints had been laid, that they might rise to heaven with the much incense added by the angel, and might be answered in God's own time and way. The voice heard from _the four horns_ of this altar--that is, from the four projecting points at its four corners, representing the altar in its greatest potency--shows us, what we might have been in danger of forgetting, that the judgment before us continues to be an answer of the Almighty to His people's prayers. Again it may be noticed that in the judgment here spoken of we deal once more with a _third part_ of the class upon which it falls. Nothing of the kind had been said under the fifth Trumpet. The inference to be drawn from these particulars is important. We learn that, however distinct the successive members of any of the three series of the Seals, the Trumpets, or the Bowls may seem to be, they are yet closely connected with one another. Though seven in number, there is a sense in which they are also one; and any characteristic thought which appears in a single member of the series ought to be carried through all its members.[220]
