Our sages say that there are three crowns - Keser Torah, Keser Kehunah, Keser Malchus - and that Moshe, Aharon, and Miriam represented these three. Moshe gave us the Torah, Aharon was the first Kohen Gadol and the father of all of them, Miriam was the ancestress of all the kings of Malchus Beis David, through her husband from Yehudah.
Our sages also say that the three great miracles in the Midbar were in the merit of these three: Moshe, the manna; Aharon, the ענני הכבוד, the clouds of glory that surrounded and protected the camp; Miriam, the באר מרים, the well of water used by the camp.
[I don't have references for all this handy but can probably find them if people need.]
Question: What do these have to do with one another? That is, can one explain why Torah = manna, Kehunah = clouds of glory, Malchus = water? I'm assuming it's not a coincidence that these three people are associated with these two different lists.
Update: Actually, I see that the miraculous third thing is not really the water - water is always the same - it's the well, the source, that followed them around. Whereas the first two, mann is itself miraculous and so are the "clouds".
Now I think about it, rain can follow people around, no problem. Somehow a well is different.
