Exodus 15:15-25 NLT

15 The leaders of Edom are terrified; the nobles of Moab tremble. All who live in Canaan melt away;
16 terror and dread fall upon them. The power of your arm makes them lifeless as stone until your people pass by, O LORD , until the people you purchased pass by.
17 You will bring them in and plant them on your own mountain— the place, O LORD , reserved for your own dwelling, the sanctuary, O Lord, that your hands have established.
18 The LORD will reign forever and ever!”
19 When Pharaoh’s horses, chariots, and charioteers rushed into the sea, the LORD brought the water crashing down on them. But the people of Israel had walked through the middle of the sea on dry ground!
20 Then Miriam the prophet, Aaron’s sister, took a tambourine and led all the women as they played their tambourines and danced.
21 And Miriam sang this song: “Sing to the LORD , for he has triumphed gloriously; he has hurled both horse and rider into the sea.”
22 Then Moses led the people of Israel away from the Red Sea, and they moved out into the desert of Shur. They traveled in this desert for three days without finding any water.
23 When they came to the oasis of Marah, the water was too bitter to drink. So they called the place Marah (which means “bitter”).
24 Then the people complained and turned against Moses. “What are we going to drink?” they demanded.
25 So Moses cried out to the LORD for help, and the LORD showed him a piece of wood. Moses threw it into the water, and this made the water good to drink. It was there at Marah that the LORD set before them the following decree as a standard to test their faithfulness to him.
