Exodus 15:26-27

26He said, “If you listen carefully to the LORD your God and do what is right in his eyes, if you pay attention to his commands and keep all his decrees, I will not bring on you any of the diseases I brought on the Egyptians, for I am the LORD, who heals you.” 27Then they came to Elim, where there were twelve springs and seventy palm trees, and they camped there near the water.
