Isaiah, Chapter 38, verses 1-8
1 Hezekiah, having received a message of death, by prayer hath his life lengthened, 8 The sun goeth ten degrees backward, for a sign of that promiseMatthew, Chapter 12, verses 1-8
1 Christ reproveth the blindness of the Pharisees concerning the breach of the Sabbath, 3 by Scriptures12
12:1 His disciples plucked the ears of corn, and ate - Just what sufficed for present necessity: dried corn was a common food among the Jews. Mar 2:23; Luk 6:1.
12:3 Have ye not read what David did - And necessity was a sufficient plea for his transgressing the law in a higher instance.
12:4 He entered into the house of God - Into the tabernacle. The temple was not yet built. The show bread - So they called the bread which the priest, who served that week, put every Sabbath day on the golden table that was in the holy place, before the Lord. The loaves were twelve in number, and represented the twelve tribes of Israel: when the new were brought, the stale were taken away, but were to be eaten by the priests only. Mat 21:6.
12:5 The priests in the temple profane the Sabbath - That is, do their ordinary work on this, as on a common day, cleansing all things, and preparing the sacrifices. A greater than the temple - If therefore the Sabbath must give way to the temple, much moremust it give way to me.
12:7 I will have mercy and not sacrifice - That is, when they interfere with each other, I always prefer acts of mercy, before matters of positive institution: yea, before all ceremonial institutions whatever; because these being only means of religion, are suspended of course, if circumstances occur, wherein they clash with love, which is the end of it. Mat 9:13.
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. Mat 12:6-8.
