Revelation 14:1

^1-2 I saw—it took my breath away!—the Lamb standing on Mount Zion, 144,000 standing there with him, his Name and the Name of his Father inscribed on their foreheads. And I heard a voice out of Heaven, the sound like a cataract, like the crash of thunder.

^2-5 And then I heard music, harp music and the harpists singing a new song before the Throne and the Four Animals and the Elders. Only the 144,000 could learn to sing the song. They were bought from earth, lived without compromise, virgin-fresh before God. Wherever the Lamb went, they followed. They were bought from humankind, firstfruits of the harvest for God and the Lamb. Not a false word in their mouths. A perfect offering.

Voices from Heaven

^6-7 I saw another Angel soaring in Middle-Heaven. He had an Eternal Message to preach to all who were still on earth, every nation and tribe, every tongue and people. He preached in a loud voice, “Fear God and give him glory! His hour of judgment has come! Worship the Maker of Heaven and earth, salt sea and fresh water!”
