Revelation 14:9-11

Then another angel, a third, followed them, saying with a mighty voice, Whoever pays homage to the beast and his statue and permits the [beast's] stamp (mark, inscription) to be put on his forehead or on his hand, He too shall [have to] drink of the wine of God's indignation and wrath, poured undiluted into the cup of His anger; and he shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb. [Gen. 19:24.] And the smoke of their torment ascends forever and ever; and they have no respite (no pause, no intermission, no rest, no peace) day or night–these who pay homage to the beast and to his image and whoever receives the stamp of his name upon him. [Isa. 34:10.]
