61 Now it happened on the second Sabbath after the first that He went through the grainfields. And His disciples plucked the heads of grain and ate them, rubbing them in their hands. 2 And some of the Pharisees said to them, "Why are you doing what is not lawful to do on the Sabbath?" 3 But Jesus answering them said, "Have you not even read this, what David did when he was hungry, he and those who were with him: 4 how he went into the house of God, took and ate the showbread, and also gave some to those with him, which is not lawful for any but the priests to eat?" 5 And He said to them, "The Son of Man is also Lord of the Sabbath."

Commentary on Luke 6:1-5
(Read Luke 6:1-5)
Christ justifies his disciples in a work of necessity for themselves on the sabbath day, and that was plucking the ears of corn when they were hungry. But we must take heed that we mistake not this liberty for leave to commit sin. Christ will have us to know and remember that it is his day, therefore to be spent in his service, and to his honour.
