Revelation 14:1

Yahweh said to him, “Go through the midst of the city, even through the midst of Jerusalem, and put a mark on the foreheads of the men who sigh and groan over all the abominations which are being done in its midst.”

But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to myriads of angels,

‘He who overcomes, I will make him a pillar in the sanctuary of My God, and he will never go out from it anymore. And I will write on him the name of My God, and the name of the city of My God, the new Jerusalem, which comes down out of heaven from My God, and My new name.

saying, “Do not harm the earth or the sea or the trees until we have sealed the slaves of our God on their foreheads.”

And I heard the number of those having been sealed, 144,000 sealed from every tribe of the sons of Israel:

And they *sang a new song before the throne and before the four living creatures and the elders. And no one could learn that song except the 144,000 who had been purchased from the earth.

and they will see His face, and His name will be on their foreheads.

The Lamb and the 144,000
