3 He said to them, "Have you not read what David did when he and his companions were hungry? 4 He entered the house of God and ate the bread of the Presence, which it was not lawful for him or his companions to eat, but only for the priests. 5 Or have you not read in the law that on the sabbath the priests in the temple break the sabbath and yet are guiltless? 6 I tell you, something greater than the temple is here. 7 But if you had known what this means, "I desire mercy and not sacrifice,' you would not have condemned the guiltless. 8 For the Son of Man is lord of the sabbath."

Commentary on Matthew 12:1-8
(Read Matthew 12:1-8)
Being in the corn-fields, the disciples began to pluck the ears of corn: the law of God allowed it, Deuteronomy 5:14. No law must be understood so as to contradict its own end. And as Christ is the Lord of the sabbath, it is fit the day and the work of it should be dedicated to him.
