Shabbat 90: Chasing Crows

Back to Shabbat topics, and minimums for carrying to be obligated in bringing a sin-offering - including a list of items that require an offering no matter how little of them you carry. In contrast: When it comes to metals, various substances were used to protect the Temple, to clean the lamps, etc. That is, when it comes to donations to the Temple, "any amount" is too little - rather, the amount has to be of actual use to the Beit HaMikdash. Plus: The "mekek," and the need to protect the scrolls in the Beit HaMikdash.
