Exodus 15:22-25

MKJV(i) 22 And Moses brought Israel from the Red Sea, and they went out into the wilderness of Shur. And they went three days in the wilderness, and found no water. 23 And when they came to Marah, they could not drink of the waters of Marah, because it was bitter. Therefore the name of it was called Marah. 24 And the people murmured against Moses, saying, What shall we drink? 25 And he cried to Jehovah. And Jehovah showed him a tree. And when he had cast it into the waters, the waters were made sweet. There He made a decree and a law for them, and there He tested them.
