At that time a Jesus went through the grainfields on the Sabbath. And His disciples were hungry, and began to b pluck heads of grain and to eat.

Now it happened that He went through the grainfields on the Sabbath; and as they went His disciples began to pluck the heads of grain.
Luke 6:1 - 5
Now it happened on the second Sabbath after the first that He went through the grainfields. And His disciples plucked the heads of grain and ate them, rubbing them in their hands.
When you come into your neighbor's standing grain, you may pluck the heads with your hand, but you shall not use a sickle on your neighbor's standing grain.
