Corn in the Bible means maize…there was no error in translation
In the Old Testament they referred to Maize in Pharoahs dream and in Joseph’s interpretation/solution
And in the New Testament, Jesus instructed his disciples to eat the corn(maize) as they walked through other farmers cornfields, if they were hungry. He was not instructing them to eat raw barley or wheat.
There are other examples, but you will encounter much opposition to this concept because it destroys the reality of those who believe the accepted lies of white people.
