Bible: Exod 15:23-25

15:23 Then they came to Marah, 1  but they were not able to drink 2  the waters of Marah, because 3  they were bitter. 4  (That is 5  why its name was 6  Marah.)

15:24 So the people murmured 7  against Moses, saying, “What can 8  we drink?” 15:25 He cried out to the Lord, and the Lord showed him 9  a tree. 10  When Moses 11  threw it into the water, the water became safe to drink. There the Lord 12  made for them 13  a binding ordinance, 14  and there he tested 15  them.
