'Healer' in the Bible

There the LORD presented to them a statute and an ordinance, and there he tested them. He said, "If you will carefully obey the LORD your God, do what he sees to be right, listen to his commandments, and keep all his statutes, then I won't inflict on you all the diseases that I inflicted on the Egyptians, because I am the LORD your healer."

"But at that time, he'll protest! He'll say, "I won't be your healer. I have neither food nor clothing in my house! You're not going to make me a leader of the people!'
