Trees and Salt

 

 

And he cried out to God and God instructed him (vayorehu) regarding a certain tree which he cast into the water, and the water became drinkable. There He gave him law and justice and there He tested them.                                   Exodus 15:25

 

            Midrashim teach that curing the waters of Marah by casting a tree into them was a miracle within a miracle.

            Midrash Sechel Tov phrases it thus:

Rabban Shimon ben Gamliel says: “Come and see how different God’s ways are from those of flesh and blood. Flesh and blood use sweet things to cure bitter ones, while the Holy One, blessed be He, marvelously performed a miracle within a miracle and used something bitter to sweeten the waters.”

            Mechilta presents the opinion of Rabbi Elazar haModa’i that it was olive wood which Moses cast into the water, “since there is nothing more bitter than olives.”

            Sechel Tov notes the parallel of the prophet Elisha’s curing of the waters of Jericho by throwing salt into them. [II Kings 2:19-23]

            Those who do not believe in miracles have suggested “scientific” explanations for curing the waters of Jericho (until today, the spring is named for Elisha).

            One suggestion is that the spring had become the breeding grounds for the malaria-spreading anopheles mosquito. When the salinity of water reaches 3.5%, the anopheles larvae cannot develop; therefore pouring salt into the water ended the outbreak of malaria. However, this suggestion is irrelevant to the Biblical account of the waters of Jericho, for three reasons:

       1] The Bible clearly presents the complaint of the residents of Jericho as undrinkable water, not as malaria (or any other disease) [v.19];

    2] Salinity of 3.5% is approximately thirty times the limit considered acceptable for drinking water.

    3] Elisha specifically instructed that the contents of a single bowl of salt be thrown into the water [verses 20-21]. Clearly, such a small quantity of salt could not have raised the water's salinity to 3.5%. (The current salinity of the water of Elisha's Spring is 30 parts per million, thus, according to the above suggestion the salinity would have to be increased by more than a factor of one-thousand!)

            A second suggestion is that the waters of Elisha’s Spring were infested with a micro-organism, which the prophet knew would be killed by pouring salt into the water.

            Assuming, for the sake of argument, that this latter suggestion is in fact the scientific explanation of the events at Jericho’s spring, it does not in any way diminish the miraculous nature of those events. That almost three millennia ago a prophet in Biblical Samaria had knowledge of microbiology is no less miraculous than taking the Biblical description at face value.

            It is instructive to note the comment of Naḥmanides (13th century), who was a physician:

It appears that the simple explanation (pshat) is that the wood had the natural ability to cure the waters of Marah, of which quality God instructed Moses.

            Quite clearly, Naḥmanides did not see accepting a “natural” explanation of a miraculous event as in any way diminishing belief in God’s power or providence. On the contrary, our Sages teach that God prefers to work through nature, rather than forcing nature to change to accommodate His will.

            The late Lubavitcher Rebbe takes the point a step further and comments:

 An open miracle is somewhat of a disappointment for God. Once all is said and done, He got His way only by ignoring the norms of our lower world, by breaking His own rules.  If He can perform miracles only by bullying Nature, He may as well concede that our world is a place the Infinite Light does not belong.
