Verse 12. They that be whole, etc. Jesus, in reply, said that the whole needed not a physician. Sick persons only needed his aid. A physician would not commonly be found with those that were in health. His proper place was among the sick. So, says he, "If you Pharisees are such as you think yourselves, already pure and holy, you do not need my aid. It would be of no use to you, and you would not thank me for it. With those persons who fed that they are sinners I may be useful; and there is my proper place." Or, the expression may mean, "I came on purpose to save sinners. My business is with them. There are none righteous; and as a physician is in his proper place with the sick, so am I with guilty and miserable sinners."
