Matthew 12:8

The Son of man is Lord even of the Sabbath-day - The change of the Jewish into the Christian Sabbath, called the Lord's day, Revelation 1:10, shows that Christ is not only the Lord, but also the truth and completion of it. For it seems to have been by an especial providence that this change has been made and acknowledged all over the Christian world.

For the Son of man is Lord even of the Sabbath day - To crown all, Christ says that he was Lord of the Sabbath. He had a right to direct the manner of its observance - undoubted proof that he is divine.

12:8 For the Son of man - Therefore they are guiltless, were it only on this account, that they act by my authority, and attend on me in my ministry, as the priests attended on God in the temple: is Lord even of the Sabbath - This certainly implies, that the Sabbath was an institution of great and distinguished importance; it may perhaps also refer to that signal act of authority which Christ afterward exerted over it, in changing it from the seventh to the first day of the week. If we suppose here is a transposition of the 7th and 8th verses, then the 8th verse is a proof of the 6th. Matthew 12:7 ,8,6.
