If any man worship the beast and his image, and receive his mark in his forehead, or in his hand ... The same shall drink of the wine of the wrath of God ... and ... be tormented with fire and brimstone. Revelation 14:9
"Corn" is obviously a mistranslation in the King James Version, since there was no corn in Egypt or anywhere in the Eastern hemisphere in biblical times.
Corn was domesticated 10,000 years ago by indigenous peoples in what is now Mexico.
