Exodus 15:26

and said, “If you diligently heed the voice of the Lord your God and do what is right in His sight, give ear to His commandments and keep all His statutes, I will put none of the diseases on you which I have brought on the Egyptians. For I am the Lord who heals you.”

15:26 heals, rapha’ (rah-phah); Strong’s #7495: To cure, heal, repair, mend, restore health. Its participial form rophe’, “one who heals,” is the Hebrew word for doctor. The main idea of the verb rapha’ is physical healing. Some have tried to explain away the biblical teaching of divine healing, but all can see that this verse speaks of physical diseases and their divine cure. The first mention of rapha’ in the Bible ( Gen. 20:17 ) refers unquestionably to the cure of a physical condition, as do references to healing from leprosy and boils ( Lev. 13:18 ; 14:3 ). Scripture affirms, “I am Yahweh your Physician.”
