Exodus 15:26-27

And He said, “If you will give earnest heed to the voice of the LORD your God, and do what is right in His sight, and give ear to His commandments, and keep all His statutes, I will put none of the diseases on you which I have put on the Egyptians; for I, the LORD, am your healer.” Then they came to Elim where there were twelve springs of water and seventy date palms, and they camped there beside the waters.
