Mark 2:28

therefore the Son of Man is Lord also of the Sabbath

The Pharisees did not abate their jealous, hawk-like watch over Jesus and His disciples for one minute. And the Lord, on His part, in no way attempted to escape from them. The lessons which He wished to convey to them would be brought out all the sooner with their vigilant presence ever near. Jesus and His disciples, on a Sabbath, were taking a walk through the fields of grain, which were just about ready for harvest. There were in those days simple, rough footpaths that have existed in Palestine since time immemorial. "If a landowner wished to raise grain in a field through which one of these paths ran, he plowed up to the very edge of the narrow path and put in his seed. " It was along one of these paths that the little company of Jesus was strolling, they were making their way slowly. And where the grain had encroached upon the path, the disciples, being hungry, pulled up the stalks. This they continued, as they went, and then rubbed the ears between the hands to extract the kernels, which they ate. Here the Pharisees complained to the Lord about the disciples, although their accusation implied a criticism of the Master for permitting the pulling of the stalks, which they identified with reaping, and the rubbing of the ears, which they identified with threshing. But Jesus defended His disciples by referring the Pharisees to the example of David, who, in a similar situation, when he and his men were in need, did not hesitate to take the showbread out of the hands of Abiathar, the high priest, and to distribute the cakes among his men, 1 Samuel 21:6. Ordinarily, only the priests were permitted to eat this bread, Leviticus 24:8, but in a case of necessity, above all, love is the fulfillment of the Law, and no one ever thought of censuring David for his action. Note: Either Ahimelech bore the additional name Abiathar, or father and son officiated together at Nobe, in this manner that David received the showbread from Ahimelech with the distinct sanction of Abiathar. The conclusion which Jesus draws from this story is brief and to the point: The Sabbath is given to man, and not man to the Sabbath. The Sabbath, as God intended it for the Jews, was to serve them as a day of rest, but His intention never had been to make them slaves of its observance and to bind them with fetters that would render life unpleasant for them. The Sabbath is thus only a means to an end. And so far as the whole question is concerned, this truth stands for all times. Jesus, as the Son of Man, as the divine-human Lord of all, has the right to abrogate the Old Testament Sabbath if He so chooses. The old injunctions concerning sacrifices, new moons, Sabbaths, etc., were in force till He came. But the body itself is of Christ, Colossians 2:16. The Third Commandment enjoins only so much upon the Christians that they gladly hear and learn the Word of God. He that does this much keeps the Third Commandment in the sense of the New Testament and need not be worried by the Sabbath fanatics of these latter days.

Summary. Jesus heals a paralytic, calls the publican Levi to be His disciple, gives a short discourse concerning tasting and the difference between the old and the new dispensation, and declares Himself to be the Lord of the Sabbath.
