61 And it came to pass on [the] second-first sabbath, that he went through cornfields, and his disciples were plucking the ears and eating [them], rubbing [them] in their hands. 2 But some of the Pharisees said to them, Why do ye what is not lawful to do on the sabbath? 3 And Jesus answering said to them, Have ye not read so much as this, what David did when he hungered, he and those who were with him, 4 how he entered into the house of God and took the shewbread and ate, and gave to those also who were with him, which it is not lawful that [any] eat, unless the priests alone? 5 And he said to them, The Son of man is Lord of the sabbath also.

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.
