Thematic Bible: The lamb on mount zion

Then I looked, and behold, the Lamb stood on Mount Zion, and with Him 144,000 [men] who had His name and His Father's name inscribed on their foreheads. And I heard a voice from heaven like the sound of great waters and like the rumbling of mighty thunder; the voice I heard [seemed like the music] of harpists accompanying themselves on their harps. And they sang a new song before the throne [of God] and before the four living creatures and before the elders [of the heavenly Sanhedrin]. No one could learn [to sing] that song except the 144,000 who had been ransomed (purchased, redeemed) from the earth. read more.
These are they who have not defiled themselves by relations with women, for they are [ pure as] virgins. These are they who follow the Lamb wherever He goes. These are they who have been ransomed (purchased, redeemed) from among men as the firstfruits for God and the Lamb. No lie was found to be upon their lips, for they are blameless (spotless, untainted, without blemish) before the throne of God.
