'Stamp' in the Bible

and that no one will be able to buy or sell, except the one who has the mark, either the name of the beast or the number of his name.

Then another angel, a third one, followed them, saying with a loud voice, “Whoever worships the beast and his image and receives the mark [of the beast] on his forehead or on his hand,

And the smoke of their torment ascends forever and ever; and they have no rest day and night—those who worship the beast and his image, and whoever receives the mark of his name.”

So the first angel went and poured out his bowl on the earth; and loathsome and malignant sores came on the people who had the mark of the beast and who worshiped his image.

And the beast (Antichrist) was seized and overpowered, and with him the false prophet who, in his presence, had performed [amazing] signs by which he deceived those who had received the mark of the beast and those who worshiped his image; these two were hurled alive into the lake of fire which blazes with brimstone.
