Exodus 15:26

And said, If thou wilt diligently hearken to the voice of the LORD the GOD, and wilt do that which right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the LORD that healeth thee.
