12:1-8 Being in the corn-fields, the disciples began to pluck the ears of corn: the law of God allowed it, De 23:25. This was slender provision for Christ and his disciples; but they were content with it. The Pharisees did not quarrel with them for taking another man's corn, but for doing it on the sabbath day. Christ came to free his followers, not only from the corruptions of the Pharisees, but from their unscriptural rules, and justified what they did. The greatest shall not have their lusts indulged, but the meanest shall have their wants considered. Those labours are lawful on the sabbath day which are necessary, and sabbath rest is to froward, not to hinder sabbath worship. Needful provision for health and food is to be made; but when servants are kept at home, and families become a scene of hurry and confusion on the Lord's day, to furnish a feast for visitors, or for indulgence, the case is very different. Such things as these, and many others common among professors, are to be blamed. The resting on the sabbath was ordained for man's good, De 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.
4. How he entered into the house of God, and did eat the showbread, which was not lawful for him to eat, neither for them which were with him, but only for the priests?—No example could be more apposite than this. The man after God's own heart, of whom the Jews ever boasted, when suffering in God's cause and straitened for provisions, asked and obtained from the high priest what, according to the law, it was illegal for anyone save the priests to touch. Mark (Mr 2:26) says this occurred "in the days of Abiathar the high priest." But this means not during his high priesthood—for it was under that of his father Ahimelech—but simply, in his time. Ahimelech was soon succeeded by Abiathar, whose connection with David, and prominence during his reign, may account for his name, rather than his father's, being here introduced. Yet there is not a little confusion in what is said of these priests in different parts of the Old Testament. Thus he is called both the son of the father of Ahimelech (1Sa 22:20; 2Sa 8:17); and Ahimelech is called Ahiah (1Sa 14:3), and Abimelech (1Ch 18:16).
