Matthew 12:3-8

But He said to them, “Have you not read what David did when he was hungry, he and those who were with him: how he entered the house of God and ate the showbread which was not lawful for him to eat, nor for those who were with him, but only for the priests? Or have you not read in the law that on the Sabbath the priests in the temple profane the Sabbath, and are blameless? Yet I say to you that in this place there is One greater than the temple. But if you had known what this means, ‘I desire mercy and not sacrifice,’ you would not have condemned the guiltless. For the Son of Man is Lord even of the Sabbath.”
