Luke 6:1-5

1Now it came to pass on a sabbath, that he was going through the grainfields; and his disciples plucked the ears, and did eat, rubbing them in their hands. 2But certain of the Pharisees said, Why do ye that which it is not lawful to do on the sabbath day? 3And Jesus answering them said, Have ye not read even this, what David did, when he was hungry, he, and they that were with him; 4how he entered into the house of God, and took and ate the showbread, and gave also to them that were with him; which it is not lawful to eat save for the priests alone? 5And he said unto them, The Son of man is lord of the sabbath.
