Revelation 14:11

14:11 And the smoke from their torture will go up forever and ever, and those who worship the beast and his image will have no rest day or night, along with anyone who receives the mark of his name.”

Revelation 2:17

2:17 The one who has an ear had better hear what the Spirit says to the churches. To the one who conquers, I will give him some of the hidden manna, and I will give him a white stone, and on that stone will be written a new name that no one can understand except the one who receives it.’
