Matthew 9:13 - Ellicott's Commentary On The Whole Bible

Go ye and learn. — The words of Hosea 6:6 — cited once again by our Lord in reference to the Sabbath (Matthew 12:7) — asserted the superiority of ethical to ceremonial law. To have withdrawn from contact with sinners would have been a formal “sacrifice,” such as Pharisees delighted to offer, and from which they took their very name; but the claims or “mercy” were higher, and bade Him mingle with them. It was the very purpose of His coming, not to call “righteous men” (again with studied reference to their own estimate of themselves), but “sinners,” and to call them, not to continue as they were, but, as St. Luke adds (the words are wanting in the best MSS. here and also in St. Mark), “to repentance.” We may, perhaps, infer further, that when the scribes were told to consider what the prophet’s words meant, there was also some reference to the context of those words. They would find their own likeness in the words, “Your goodness is as a morning cloud;... they... have transgressed the covenant; there have they dealt treacherously against me” (Hosea 6:4; Hosea 6:7).
