“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.”
King James Version (KJV)
15:2 The song was sung while the angels were coming out, with their plagues, who are therefore mentioned both before and after it, verses 1 - 6. #Rev 15:1 |- 6 And I saw as it were a sea of glass mingled with fire - It was before clear as crystal, #Rev 4:6|, but now mingled with fire, which devours the adversaries. And them that gained, or were gaining, the victory over the wild beast - More of whom were yet to come. The mark of the beast, the mark of his name, and the number of his name, seem to mean here nearly the same thing. Standing at the sea of glass - Which was before the throne. Having the harps of God - Given by him, and appropriated to his praise.
Re 15:2 I saw as it were a sea of glass. In Re 4:6 "the sea of glass, clear as crystal", was seen about the throne of God. It is the emblem of the calmness and purity of God's rule. Here the sea is mingled with fire, a symbol always denoting judgments. This shows that the time for judgments, coming from the throne of God, has come. And them that had gotten the victory over the beast. These are the redeemed of Re 14:1, who are there seen standing with the Lamb on Mount Zion. They now engage in triumphant songs over the approaching overthrow of their great enemy. Having the harps of God. Musical instruments wholly dedicated to his praise.
