Rashi on II Samuel
Who will give me water to drink. Our Rabbis said,15Baba Kama 60b. See Rashi there. he [Dovid] needed to ask a [halachic] question from the Sanhedrin court that sat at the gate of Beis Lechem.16The “water” of our verse is referring to Torah which is compared to water. See Devorim Raboh 7:3.
