This episode completes the laws of floor maintenance on Shabbat and opens the topic of sound-making prohibitions. We review why spreading oil or scrubbing floors is restricted—even on paved surfaces—due to concerns of leveling ground and related actions. The discussion extends to placing heavy barrels on the ground, the risk of creating furrows, and why lifting rather than dragging is required.

The episode then introduces the laws of making sounds on Shabbat: musical instruments and music-like sounds are prohibited, while non-musical sounds—such as knocking on a door—are generally permitted. Practical cases include clapping, noise-making to scare birds, soothing a child, dripping water for sound, and using noise to wake someone. The guiding principle is whether the sound is musical, pleasant, and instrument-like, or merely functional.
