If he tied a knot that could be untied with one hand, that was all right; but if he took two hands to untie it, then he had broken the Sabbath. He even had to be careful about sitting in a chair, for if he happened to drag his chair across the dirt floor the Pharisees said that he was plowing, which was a great sin on the Sabbath Day. It was forbidden to make a fire on the Sabbath. And so, if a woman wanted hot food, she had to cook it the day before, and keep it warm. But that did not mean that she could set it on a stove. For the stove might get hotter than it was, and make the food hotter, and that was just the same as making a fire. The only safe way to keep a meal hot was to wrap the dishes in cloth or pigeon feathers.
Jesus did not think that rules like this were what the Scriptures meant when they said, "Remember the sabbath day, to keep it holy." He did not think that this was the way to honor God. And because Jesus did not agree with them about the Sabbath, the Pharisees were always watching for a chance to put him in the wrong.
Once, when Jesus and his disciples were walking through a field of grain on the Sabbath Day, the Pharisees saw that the disciples were eating some of the grain. There was nothing wrong with eating it, if they were hungry. But the trouble was that in order to get the grain they had to pluck the ears. That, said the Pharisees, was harvesting! Moreover, they had to take the ripe ears and rub them in their hands to get rid of the chaff. The Pharisees thought that that was just the same as threshing! Such things to do on the Sabbath Day! The Pharisees stopped the disciples, and demanded to know why they were doing something that was against the Law.
It was really Jesus with whom they wanted to pick a quarrel, and so Jesus answered for the disciples:
"Why, you must have read in the Scriptures that King David and his soldiers once went into the Temple and ate some of the holy bread which only a priest is allowed to eat. Surely if David could do a thing like that, my disciples can pick a few ears of grain in a field!
"You don't understand what the Sabbath is for," Jesus went on. "We aren't supposed to be slaves to the Sabbath; this day is meant to do us good. The Sabbath was made for man; man was not made for the Sabbath."
Then he added something else, which took the Pharisees by surprise:
"The Son of man is Lord also of the Sabbath."
