This week's parasha has the famous water from the rock story. Rabbi Shapira of Lublin compares water to b'nai yisrael. He speaks of how powerful water is, how it can move mountains, flood plains, etc. etc. but he says that's only when it is liquid. If it is frozen, it doesn't accomplish anything. Similarly B'nai Yisrael, when they are enthusiastic and flowing, they can do anything, but when they are frozen and apathetic, they cannot do a thing.
Isaiah says :all who are thirsty. come and drink. Water= Torah there.
Miriam dies in this parasha and the water dries up. The sages said Israel had water in the desert because of her merit
