Menahot 31: Torn Torah Scrolls and Poetic Mezuzahs

More from Rabbi Shimon Shezuri - with a question of untithed produce that was mixed with a greater portion of tithed produce. Rabbi Tarfon gives him a solution - and the Gemara suggests several other solutions Rabbi Tarfon could have made (though the Gemara also then explains why he didn't make them). Also, going back to the scribal requirements - when a tear requires replacement, with recognition of worn parchments (vellum), and how they were protected. Plus, the requirements of writing out the text for a mezuzah.
