but you may not pour [it] out on broken [ground].<span class="x" onmousemove="('comment',' Rashi: Broken ground contains shallows and cavities where the water will gather. Instead of soaking in, and will thereby cause fermentation. Jast.: the place where water poured out would remain stagnant.');">⁸</span> While another [Baraitha] taught: You may pour [it] out on broken ground? - There is no difficulty: here it means that it [the water] is abundant, so that it collects;<span class="x" onmousemove="('comment',' Hence it may not be poured out there.');">⁹</span>
