Luke 5:31

And Jesus answering, said unto them,.... Knowing that they aimed at him; though, according to this evangelist, they only mentioned his disciples, however, he takes up the cause, and vindicates both himself and them, by observing to them the following proverb;

they that are whole need not a physician, but they that are sick: suggesting hereby, that as such who are in good health, who are free from all diseases, wounds, bruises, and putrefying sores, stand in no need of the advice and assistance of a physician, or surgeon, but such who have either distempers or sores on their bodies; so they, the Scribes and Pharisees, who, in their own opinion, were free from the disease of sin, original and actual, and touching the righteousness of the law, were blameless, stood not in any need of him, the physician, who came to cure the maladies of the souls, as well as of the bodies of men; but such persons, who not only are sick with sin, but sick of it, who are sensible of it, and desire healing: and therefore this was the reason of his conduct, why he conversed with sinners, and not with the Scribes and Pharisees; his business, as a physician, lying among the one, and not the other; Matthew 9:12.

Mark 2:17.
