Revelation 14:9-11

ECB(i) 9
And the third angel follows them, speaking in a mega voice, If anyone worships the beast and his icon and takes his tattoo in his forehead or in his hand, 10 the same drinks of the wine of the fury of Elohim, mingled undiluted in the cup of his wrath; and is tortured in fire and sulphur in the sight of the holy angels and in sight of the Lamb: 11 and the smoke of their torture ascends to the eons of the eons: and they who worship the beast and his icon - also if any take the tattoo of his name they have no rest day and night.
