✋My Mouth or My Whole Body?
What if only your hand is dirty, or only your hand is inside a bathroom? Rav Huna says you may still say Shema, because the verse says 'Let every soul (neshama) praise God', so what matters is the mouth that speaks the praise. Rav Chisda says no: Psalms says 'All my bones shall say', so your whole body must be in a clean place.
Amud a 🚶Something Passing By
What if something dirty is being carried past you while you say Shema? Abaye says it is allowed, and Rava says it is not. The Gemara compares the case to other laws, to work out who is right.
Amud a 🤷It's OK to Say 'I Don't Know'
Rav Yosef asked Rav Huna how high a wall must be to make a separate space. Rav Huna honestly said, 'I don't know' for a wall of three to nine handbreadths, but ten handbreadths is surely separate. Abaye said he did well. Rava summed it up: less than three counts as joined, ten is a separate place.
