Exodus 15:26-27

15:26 He said, “If you will diligently obey the Lord your God, and do what is right in his sight, and pay attention to his commandments, and keep all his statutes, then all the diseases that I brought on the Egyptians I will not bring on you, for I, the Lord, am your healer.”

15:27 Then they came to Elim, where there were twelve wells of water and seventy palm trees, and they camped there by the water.
