Matthew 12:4
How he entered the house of God and ate the bread of the Presence, which it was not lawful for him to eat nor for those who were with him, but only for the priests? The David argument is not analogically precise — the bread of the Presence was not a Sabbath regulation — but it establishes the principle: the law serves human need, not the reverse. The bread lawful only for priests was given to David in his need by the priest Ahimelech. The precedent cuts against the Pharisees' rigid application of regulations regardless of human circumstances.
