Matthew 12:2-7

2But when the Pharisees saw it, they said to him, "Look, your disciples are doing what is not lawful to do on the Sabbath."

3He said to them, "Have you not read what David did when he was hungry, and those who were with him:

4how 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?

5Or have you not read in the Law how on the Sabbath the priests in the temple profane the Sabbath and are guiltless?

6I tell you, something greater than the temple is here.

7And if you had known what this means, 'I desire mercy, and not sacrifice,' you would not have condemned the guiltless.
