Elisha went out to the spring, threw salt in it, and said, ‘This is what the Lord says: “I have healed this water. No longer will death or unfruitfulness result from it.” ’
So he cried out to the Lord, and the Lord showed him a tree. When he threw it into the water, the water became drinkable. The Lord made a statute and ordinance for them at Marah, and he tested them there.
Then the man of God asked, ‘Where did it fall? ’ When he showed him the place, the man of God cut a piece of wood, threw it there, and made the iron float.
