Water is often used as a metaphor for Torah. The Talmud (Taanit 7a) explains that “just as water leaves a high place and flows downward to a low place, so does Torah knowledge flow away from those who are arrogant and toward those who are humble.” Furthermore, just as water nourishes and sustains the “thirsty soil” and “dry ground,” the Bible is the source of our spiritual nourishment.
