All three of the Synoptic Gospels record the incident of Jesus and His disciples passing through the grainfields on a Sabbath.
On a Sabbath, while he was going through the grainfields, his disciples plucked and ate some heads of grain, rubbing them in their hands. But some of the Pharisees said, “Why are you doing what is not lawful to do on the Sabbath?” (Luke 6:1-2 ESV)
I thought I would put together some photos to help you visualize what happened here. First, we have a photo of a wheat field below Mount Tabor. The photo is made looking north west from near the site of ancient En-dor. The area is famous as the home of the medium visited by King Saul (1 Samuel 28:7).
Now, imagine the disciples taking grain in their hands.
And then rubbing the heads to separate the grain from the chaff.
The last two photos were made in the vicinity of Mount Nemrut in eastern Turkey. Larger images, suitable for use in teaching, are available by clicking on the photos.
