Jesus makes reference to King David and his men from 1 Kings 13 and also Leviticus and Deuteronomy in refuting the Pharisees' accusation that He was breaking the law of the Sabbath. Jesus first insults his accusers by asking them, "have you not read...?" Certainly they had, but Jesus is pointing out once again, that their interpretation of the law was legalistic, in the same manner in which Lucifer uses Scripture. What does the law (of Moses) say of healing on the Sabbath? Jesus demonstrates His Lordship over the Sabbath and how his accusers have things upside down. We look to the Old Testament and the Catechism of the Catholic Church to point out Jesus fulfilling that which was written in the Law and writings.
