23When they came to Marah, they could not drink its water because it was bitter. (That is why the place is called Marah. Marah means bitter. )
24So the people grumbled against Moses, saying, “What are we to drink?”
25Then 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.
