61 One sabbath while Jesus was going through the grainfields, his disciples plucked some heads of grain, rubbed them in their hands, and ate them. 2 But some of the Pharisees said, "Why are you doing what is not lawful on the sabbath?" 3 Jesus answered, "Have you not read what David did when he and his companions were hungry?

(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.
