Thematic Bible: The lamb on mount zion

Then, in my vision, I saw the Lamb standing on Mount Zion. With him were a hundred and forty-four thousand men, with his name and the name of his Father written on their foreheads. And I heard a sound from Heaven, 'like the sound of many waters,' and like the sound of a loud peal of thunder; the sound that I heard was like the music of harpers playing on their harps. They are singing what seems to be a new song, before the throne, and before the four Creatures and the Councillors; and no one was able to learn that song except the hundred and forty-four thousand who had been redeemed from earth. read more.
These are the men who never defiled themselves in their intercourse with women; they are as pure as virgins. These are the men who follow the Lamb wherever he goes. They were redeemed as the first-fruits of mankind for God and for the Lamb. 'No lie was ever heard upon their lips.' They are beyond reach of blame.
