"And I saw another sign in heaven, great and wonderful, seven angels having the seven last plagues; for by these, the wrath of God is completed. And I saw as it were a transparent sea mingled with fire; and those who had obtained the victory over the wild beast, and over his image, and over the number of his name, standing on the transparent sea, having harps of God. And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and wonderful are thy works, O Lord God Almighty; just and true are thy ways, king of nations! Who should not fear thee, O Lord, and glorify thy name? for thou only art holy; for all nations will come and worship before thee; for thy judgments are manifested." Rev.15:1-4.

This appears to close the vision commencing with the sixth verse of the 14th chapter, and to be independent of the remaining portion of the 15th chapter.

These "seven angels," in the subsequent vision, discharge the contents of the vials of God's wrath; but the epoch here presented is evidently subsequent to that fulfilment; for the imitation of the "Song of Moses," must follow the infliction of the judgments which call forth that song of rejoicing. They had here completed the wrath of God, the manner of which act is subsequently shown in a separate vision.

The "sea of glass," must represent an elevation above the earth. For those stationed there had gotten the victory over the beast and his image, had escaped the wrath to be poured on those who worshipped those powers (14:9), had been gathered when the harvest of the earth was reaped (14:16), being then caught up to meet the Lord in the air (1 Thess.4:17), and now, the clusters of the vine of the earth having been gathered and cast into the wine-press of the wrath of God (14:19), they rejoice above the fires of earth, witnesses of the manifestations of God's judgments. They have come out of all their tribulations, and evidently synchronize with the palm-bearing multitude (Rev.7:9), the hundred and forty-four thousand on Mount Zion (14:1), and the multitude in heaven who sing Alleluia over the judgment of the great harlot, 19:1.

"The song of Moses," was that sung by the Israelites when the Egyptians had perished in the waters of the Red Sea, and they were safely encamped on its further shore. The Lord had triumphed gloriously over the enemies of Israel, had buried the horse and his rider in the sea, and was about to plant his people in the mountain of his inheritance, -- in the place which he had made for them to dwell in, -- in the sanctuary which he had established, Ex.15:1-21. The analogy requires that when this corresponding song is sung, the ransomed of the Lord shall have correspondingly witnessed the overthrow of the adversaries of Jehovah, and shall themselves have escaped from the perils of the many waters which had threatened to engulf them.

The judgments of God being manifested on the nations of the ungodly, there are none remaining, only "the nations of them which are saved," 21:24. As these will all walk in the light of the new Jerusalem, those on the sea of glass may well sing:

"Great and marvellous are thy works, Lord God Almighty! Just and true are thy ways, thou King of saints!
Who shall not fear thee, O Lord, and glorify thy name? For thou only art Holy:
For all nations shall come and worship before thee; For thy judgments are made manifest."

In accordance with the foregoing view, this synchronizes with the "new song" sung by those who are redeemed from every nation, kindred, tongue and people (5:9), who are afterwards seen standing with the Lamb on Mount Zion, 14:3.
