Revelation 15:2: “And I” [John] “saw as it were a sea of glass mingled with fire:” [The Most High's throne room in heaven] “and them” [Those of the 144,000/Servants of God] “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.”
