TSK · Revelation 21:17

And I heard the number of them which were sealed: [and there were] sealed an hundred [and] forty [and] four thousand of all the tribes of the children of Israel.

And they sung as it were a new song before the throne, and before the four beasts, and the elders: and no man could learn that song but the hundred [and] forty [and] four thousand, which were redeemed from the earth.
