Matthew 12:2-7

2But the Pharisees, when they saw it, said unto him, Behold, thy disciples do that which it is not lawful to do upon the sabbath.

3But he said unto them, Have ye not read what David did, when he was hungry, and they that were with him;

4how he entered into the house of God, and ate the showbread, which it was not lawful for him to eat, neither for them that were with him, but only for the priests?

5Or have ye not read in the law, that on the sabbath day the priests in the temple profane the sabbath, and are guiltless?

6But I say unto you, that one greater than the temple is here.

7But if ye had known what this meaneth, I desire mercy, and not sacrifice, ye would not have condemned the guiltless.
