Revelation 15:3-8

3 and they sing the song of Moses, servant of God, and the song of the Lamb, saying, `Great and wonderful [are] Thy works, O Lord God, the Almighty, righteous and true [are] Thy ways, O King of saints,
4 who may not fear Thee, O Lord, and glorify Thy name? because Thou alone [art] kind, because all the nations shall come and bow before Thee, because Thy righteous acts were manifested.'
5 And after these things I saw, and lo, opened was the sanctuary of the tabernacle of the testimony in the heaven;
6 and come forth did the seven messengers having the seven plagues, out of the sanctuary, clothed in linen, pure and shining, and girded round the breasts with golden girdles:
7 and one of the four living creatures did give to the seven messengers seven golden vials, full of the wrath of God, who is living to the ages of the ages;
8 and filled was the sanctuary with smoke from the glory of God, and from His power, and no one was able to enter into the sanctuary till the seven plagues of the seven messengers may be finished.

Revelation 15:3-8 Meaning and Commentary

INTRODUCTION TO REVELATION 15

This chapter is a preparation to the pouring out of the seven vials, and contains a vision of the seven angels in heaven that should do this work, of a chorus of harpers on this occasion, and of the same seven angels coming out of the temple, and receiving the vials, in order to execute their commission. The vision of the seven angels, having the seven last plagues, so called because filled up with the wrath of God, is said to be a sign, great and marvellous, Re 15:1 a sea of glass, mingled with fire, is seen, with persons standing on it, described by the victory they had got over the beast, his image, mark, and number of his name; by having the harps of God in their hands, and by the song they sung, called the song of Moses, and of the Lamb; in which they ascribe to Christ deity, dominion over the saints, omnipotence, justice, truth, and holiness; give him glory, celebrate his works, commend his ways, and suggest that he ought to be the object of the fear and worship of all, Re 15:2-4. Next the temple in heaven is seen opened, out of which come the seven angels, described by the place they came from, the temple; by what they had, the seven plagues; by their habit, clothed in pure white linen; and by their golden girdles about their breasts, Re 15:5,6 to whom one of the four living creatures, made mention of in Re 4:6 delivers to them seven golden vials full of divine wrath, upon which the temple is filled with smoke from the Lord; so that it was not possible for anyone to enter into it, until these seven plagues were ended, Re 15:7,8.
