(7) I will have mercy, and not sacrifice.--Yet a third argument follows from the Old Testament (Hosea 6:6). The teachers or interpreters of the Law had failed to catch the meaning of the simplest utterances of the prophets. "Mercy and not sacrifice," moral and not positive duties, these made up the true life of religion, and were alone acceptable to God. It was because they had inverted the right relation of the two that they had, in this instance, condemned those whom our Lord now declares to have been in this respect absolutely guiltless.

Verse 7. - Matthew only. But if ye had known what this meaneth, I wilt have mercy, and not sacrifice, ye would not have condemned the guiltless (on the quotation, see Matthew 9:13, note). Had you learned the simple Bible truth that God places the exercise of your moral faculties, particularly those of kindness, above merely external observances, you would not have committed this sin of taking up the position of wrong judges. He traces their error up to its true source, ignorance of the first principles of religion, ignorance of what God really desires. Condemned. Formally and officially (καταδικάζω). The guiltless. As were the very priests (ver. 5).

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.But if ye had known what this meaneth, The passage of Scripture in Hosea 6:6

I will have mercy, and not sacrifice; of the sense of which, see Gill on Matthew 9:13.

ye would not have condemned the guiltless. Our Lord taxes the Pharisees both with ignorance of the Scriptures, in which they pretended to be very knowing, and took upon them to be the interpreters of; and with inhumanity, for condemning innocent persons, the apostles, for rubbing a few ears of corn, for the refreshment of nature; which they would never have done, had they understood the word, and will of God; who prefers acts of humanity, compassion, and mercy, to the observance of rites and ceremonies; or had they the common affections of human nature, and those bowels of compassion which one man ought to show to another.
