I found death and decomposition. As it was, we only had to deal with the taste, smell and thought. Though many times I have been grateful for cisterns, I am all for fountains of living waters. Cisterns break and leak. Cisterns get contaminated.
Cisterns allow water to stagnate.
Therefore, those who, having a fountain, use cisterns are foolish, dangerously foolish. These lessons apply to the spiritual dimension. Those who turn away from the Fountain of Living Water commit the worst evil imaginable. When they turn to defective cisterns of their own making, they multiply their evil. Furthermore, if I try pouring the Living Water into a cistern I will be tempted to skip the Fountain in favor of the cistern.
