Exodus 15:26 and He said: 'If thou wilt diligently hearken to the voice of the LORD thy God, and wilt do that which is right in His eyes, and wilt give ear to His commandments, and keep all His statutes, I will put none of the diseases upon thee, which I have put upon the Egyptians; for I am the LORD that healeth thee.' (See NAS RSV)
Isaiah 3:7 In that day he will cry out, saying, I will not be a healer; for in my house is neither bread nor clothing. You shall not make me ruler of the people. (WEB KJV JPS ASV DBY WBS NAS RSV)
