Matthew 9:12 - Ellicott's Commentary On The Whole Bible

They that be whole. — Literally, They that are strong. St. Luke gives, with a more professional precision, “They that are in health.” That, speaking from the thoughts and standpoint of those addressed (which in another than our Lord we might term grave irony), which enters so largely into our Lord’s teaching, appears here in its most transparent form. Those of whom He speaks were, we know, suffering from the worst form of spiritual disease, but in their own estimation they were without spot or taint, and as such. therefore, He speaks to them. On their own showing, they ought not to object to His carrying on that work where there was most need of it. The proverb cited by Him in Luke 4:23 shows that it was not the first time that He had referred to His own work as that of the Great Physician.
