A puzzling event takes place, wherein people start prophesying in the main camp when the ‘spirit of Hashem rests on them’. Two men in particular continue after the others stop. A lad runs to Moshe to report that אלדד ומידד מתנבאים במחנה – “Eldad and Medad are prophesying in the camp”. Yehoshua leapt up and advised Moshe to imprison them. Moshe retorted that he wished everyone were a prophet. End of episode.
What exactly is the issue? Moshe’s reaction seems like a no-brainer? What is wrong with prophecy? And why the extra word במחנה – where else would they be?
Rashi quotes the Gemara in Sanhedrin that re-frames what transpired. They foresaw that משה מת, יהושע מכניס – “Moshe will die and Yehoshua will take the lead into Israel,”. Yehoshua took great umbrage at their outrageous claim, and Moshe calmed him by pointing out the prophetic nature of their words.
But where does the Gemara get the idea that these were the words of Eldad and Medad?
The Maharil Diskin explains that a look at Moshe’s beginning hints at his downfall. When the abandoned Moshe is found by Pharaoh’s daughter, she names him Moshe – כי מן המים משיתהו – “for I drew him out of the water”. There is an emphasis on the definite article – “the water”. Naming him משה was contingent on משיתהו – it wasn’t specific to “the” water. In other words, she could well have said ממים משיתהו – “for I drew him from water,”. The letters נ and ה seem extra as a result.
Returning to Eldad and Medad, the Torah stresses their prophecy was במחנה – which can literally be rendered מח-נ-ה – “erase the נה”. Erase the נה from how Moshe was named, and it says ממים משיתהו – the word ממים has the initial letters of משה מת יהושע מכניס. The emphasis of במחנה perhaps explains how Chazal understood what they truly foresaw – re-framing our understanding of the episode.
