“So he cried out to the Lord, and the Lord showed him a tree. When he cast it into the waters, the waters were made sweet. There He made a statute and an ordinance for them. And there He tested them,” (Exodus 15:25)
Helpless and angry, Israel berated Moses because Marah’s water was toxic. He cried to the Lord for help and at the Lord’s command, Moses tossed a Tree into the water and it became drinkable.
Tell me, once the Tree submerged, how did the Israelites know the water was pure? Did God use special effects like Hollywood? Was there a magic wave that changed the appearance of the water?
