"The Keli Yakar [Rav Shelomo Efrayim Luntschitz of Prague, 1550-1619] offers a remarkable explanation. He notes that when the Torah reports the death of Miriam, it simply states that she died and was buried. No mention is made of eulogies or mourning, in contrast to the Torah’s accounts of the deaths of Aharon and Moshe, where it is explicitly mentioned that the nation wept for the loss of their leader. It seems, the Keli Yakar observes, that the people were not moved by Miriam’s death, and did not properly eulogize or mourn for her. They failed to appreciate the fact that their constant water supply was directly and solely due to her. God therefore took away the well so that the people would appreciate what an exceptionally righteous person they lost. As they did not properly appreciate the miracle of the well and Miriam’s greatness which provided it, it had to be taken away." (Shirat Devorah)
