'Corn fields' in the Bible

AT that time Jesus walked through corn-fields on a sabbath-day; and his disciples were hungry, and began to pluck the ears of corn, and to eat.

And he was walking through the cornfields on the sabbath; and his disciples as they went on the road plucked the ears of corn.

AND it came to pass on the sabbath after the second day of the passover, that he was passing through the cornfields; and the disciples plucked the ears of corn, and did eat, rubbing them out in their hands.
