19 When Pharaoh’s horses, chariots and horsemen went into the sea, the Lord brought the waters of the sea back over them, but the Israelites walked through the sea on dry ground.
20 Then Miriam the prophet, Aaron’s sister, took a tambourine in her hand, and all the women followed her, with tambourines and dancing.
21 Miriam sang to them:‘Sing to the Lord,for he is highly exalted.Both horse and driverhe has hurled into the sea.’
22 Then Moses led Israel from the Red Sea and they went into the Desert of Shur. For three days they travelled in the desert without finding water.
23 When they came to Marah, they could not drink its water because it was bitter. (That is why the place is called Marah.)
24 So the people grumbled against Moses, saying, ‘What are we to drink?’
25 Then Moses cried out to the Lord, and the Lord showed him a piece of wood. He threw it into the water, and the water became fit to drink.There the Lord issued a ruling and instruction for them and put them to the test.
