Son of man, cause thy belly to eat, and fill thy bowels with this roll that I give thee. Then did I eat it; and it was in my mouth as honey for sweetness. Ezekiel 3:3
"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.
