Exodus 15:26-27

saying, “If you will diligently listen to the voice of the LORD your God, and do that which is right in his eyes, and give ear to his commandments and keep all his statutes, I will put none of the diseases on you that I put on the Egyptians, for I am the LORD, your healer.” Then they came to Elim, where there were twelve springs of water and seventy palm trees, and they encamped there by the water.
