'Grainfields' in the Bible

At that season Jesus went on the sabbath day through the grainfields; and his disciples were hungry and began to pluck ears and to eat.

And it came to pass, that he was going on the sabbath day through the grainfields; and his disciples began, as they went, to pluck the ears.

Now it came to pass on a sabbath, that he was going through the grainfields; and his disciples plucked the ears, and did eat, rubbing them in their hands.
