cure, (cause to) heal, physician, repair, X thoroughly, make whole

Concise Bible Dictionary:

The Lord said, “They that be whole need not a physician,” showing that then, as now, the work of such persons was to cure diseases. In the Old Testament the word is rapha, “to heal,” and in Genesis 50:2 Joseph called upon such to embalm the body of his father, a certain amount of chemical knowledge being needed also for that. The Lord promised to the Israelites that if they obeyed Him, He would preserve them from the diseases that were common in Egypt. On the other hand, there are many proofs in scripture that diseases were sent as a punishment for the sins of His people. For any remedy for such, their eyes should have been directed to Him who was disciplining them. Of Asa it is said, “he sought not to the Lord, but to the physicians,” which probably means those associated with magic (2 Chron. 16:12).
The Christian should surely be cast upon the Lord in his sicknesses, and be exercised as to why they are sent or allowed, though doubtless he may use the means, without trusting to them apart from the blessing of God upon them. Jehovah Himself was the physician of His people Israel, ready at all times to heal and restore them (Jer. 8:22). Job, in the bitterness of his soul, found his friends to be physicians of no value. They did not understand his case, and only added to his misery (Job 13:4).
In the New Testament ἰατρός. signifies “healer.” The Lord Jesus was the Great Healer not only of the diseases of the body, but of the soul (Luke 4:23). A woman who had spent her all on physicians without relief obtained from Him an immediate cure (Luke 8:43). Luke was called “the beloved physician,” though there is no information as to his practicing this profession (col. 4:14).
