The difference seems to lie in the prepositions – he cried “to” Yahweh, but the people murmured “against” Moses. 68 sn U. Cassuto notes that here is the clue to the direction of the narrative: Israel needed God’s instruction, the Law, if they were going to enjoy his provisions (Exodus, 184). 69 sn S. R. Driver (Exodus, 143) follows some local legends in identifying this tree as one that is supposed to have – even to this day – the properties necessary for making bitter water sweet. B. Jacob (Exodus, 436) reports that no such tree has ever been found, but then he adds that this does not mean there was not such a bush in the earlier days. He believes that here God used a natural means (“showed, instructed”) to sweeten the water. He quotes Ben Sira as saying God had created these things with healing properties in them. 70 71 72 73 74 sn The whole episode was a test from God. He led them there through Moses and let them go hungry and thirsty. He wanted to see how great their faith was. 75 76 77 78 79 80 sn The name I Yahweh am your healer comes as a bit of a surprise. One might expect, “I am Yahweh who heals your water,” but it was the people he came to heal because their faith was weak. God lets Israel know here that he can control the elements of nature to bring about a spiritual response in Israel (see Deut 8). 81
