Exodus 15:22–27
22 aThen Moses 1led Israel from the 2Red Sea, and they went out into bthe wilderness of cShur; and they went three days in the wilderness and found no water.
23 When they came to aMarah, they could not drink the waters 1of Marah, for they were 2bitter; therefore it was named 3Marah.
24 So the people agrumbled at Moses, saying, “What shall we drink?”
25 Then he acried out to the Lord, and the Lord showed him ba tree; and he threw it into the waters, and the waters became sweet.
There He cmade for them a statute and regulation, and there He dtested them.
26 And He said, “aIf you will give earnest heed to the voice of the Lord your God, and do what is right in His sight, and give ear bto His commandments, and keep all His statutes, cI will put none of the diseases on you which I have put on the Egyptians; for I, dthe Lord, am your healer.”
27 Then they came to aElim where there were twelve springs of water and seventy date palms, and they camped there beside the waters.
