The impurity of Tzara'at and the impurity of the creepy-crawlies -- can one be inferred from the other? Different ways one happens upon tumah - vs. the tumah and experience of Tzara'at. Also: Tzitzit. With Sha'atnez. Literally. Plus: Learning from verses in proximity to each other. And: Some musing on the surreality of the discussions of these mitzvot (and Yardaena's story of sha'atnez). Also: why the blind are obligated in Tzitzit.
