And I saw as it were a sea of glass mingled with fire: and them that had gotten the victory over the beast, and over his image, and over his mark, and over the number of his name, stand on the sea of glass, having the harps of God.

I saw. A sea of glass, mingled with fire: by which are signified the storms and dangers which they had happily passed: now they are said to be singing the canticle of Moses after he had passed the Red Sea, Cantemus Domino, "Let us sing to the Lord "As Moses was a figure of Christ, and the Israelites of the Christians, so it is now called the canticle of the Lamb. (Witham)
By the sea of glass is meant the firmament that makes the floor of heaven, which is here said to be mingled with fire, in allusion to the troubles and persecutions which the faithful, who are standing on this sea, have sustained. The beast that is here mentioned is an allusion to idolatry or heresy (Pastorini)
