" There are four on whose pots the Holy One, blessed he, knocked, only to find them filled with piss, and these are they: Adam, Cain, the wicked Balaam, and Hezekiah."

Again, an abrupt transposition from the divine to the domestic, from upper to lowly spheres, occurs in the midrash. The homely image of the Holy One knocking on pots apparently derives from the practice of tapping on a clay or earthen pot to hear its ring in order to decide if it is worthy of holding wine. In current Hebrew usage, the expression 'to assess or gauge someone's pot' still denotes taking in the measure of a person's character. From Adam's answer to God, we learn that he turned out to be a pisspot. "
