Exodus 15:22-25
22 So 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, for they were 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 unto the Lord; and the Lord shewed him a tree, which when he had cast into the waters, the waters were made sweet: there he made for them a statute and an ordinance, and there he proved them,
-While making the long journey between Egypt and the Promised Land, the thirsty Hebrew came upon a watering hole. While usually a sight for sore eyes, in this case the waters were bitter and undrinkable. This otherwise bad situation was made good by two things; 1) Moses cried out to the Lord, which is always a good start and 2) The Lord showed Moses a tree which, when cast into the bitter waters, made them sweet. Not just drinkable, not just tolerable, but sweet as honey. Notice that the tree does not soak up the bitter water like a sponge, the water is still there, but it is changed into something good, something profitable. In our journeys we will often come upon waters that are too bitter to be swallowed. But the Lord has another tree, fashioned into the shape of a cross, that when added to your circumstance will take away the bitter sting. It won’t dry up your waters, they will still be there, but they will be changed into something profitable and sweet to the taste.
