Luke 6:5

Lord also--rather "even" (as in Mat 12:8). of the sabbath--as naked a claim to all the authority of Him who gave the law at Mount Sinai as could possibly be made; that is, "I have said enough to vindicate the men ye carp at on My account: but in this place is the Lord of the law, and they have His sanction." (See Mar 2:28.)

In this chapter we have Christ's exposition of the moral law, which he came not to destroy, but to fulfil, and to fill up, by his gospel. I. Here is a proof of the lawfulness of works of necessity and mercy on the sabbath day, the former in vindication of his disciples' plucking the ears of corn, the latter in vindication of himself healing the withered hand on that day (Luk 6:1-11). II. His retirement for secret prayer (Luk 6:12). III. His calling his twelve apostles (Luk 6:13-16). IV. His curing the multitudes of those under various diseases who made their application to him (Luk 6:17-19). V. The sermon that he preached to his disciples and the multitude, instructing them in their duty both to God and man (v. 20-49).

6:5 Lord, even over the Sabbath: The saying is a play on words with a double meaning. First, son of man often means “human being,” so Jesus affirmed that the Sabbath was made to serve human beings. Son of Man was also a title for the Messiah (see Dan 7:13-14). Jesus is Lord of the Sabbath because he created it.
