Few textual witnesses of the Palestinian Talmud exist. There is only one complete manuscript (MS Leiden Scaliger 3), and then another exemplar which includes order Zeraim (and tractate Sotah; MS Vatican Heb. 133), plus an assortment of fragments (now collated and described in Sussman, Otzar Kitvei Yad Talmudiyyim [Review Pending]). Quotations of Yerushalmi in medieval literature are thus helpful in determining the original text of the Yerushalmi and in pointing out where early readers of the text thought an emendation or a paraphrase were in order. Most medieval quotations tend to be lifted verbatim from earlier quotations, mostly the commentary of R. Hananel and the code of R. Isaac Alfasi, and so any quotation not taken from these sources is especially valuable, as are quotations from Eastern works. The earlier, of course, the better.
Looking for midrashic material in a manuscript of Judaeo-Arabic sermons on the Torah, MS JTS 1803, I found a quotation of Yerushalmi, that I offer here for the first time (PDF). The manuscript (dated by the IMHM to the “12th-13th century”) is fragmented, and was obviously part of a larger compendium of sermons, similar to the Sheiltot, but in Arabic rather than Aramaic. Each sermon begins with a quotation from the Babylonian Talmud, and one, on Parshat Vayakhel, begins with a quotation from the Yerushalmi, clearly marked “Yerushalmi,” in large letters. Most of the material is not found in the medieval quotations I know of (which I found by using Moshe Pinchuk’s wonderful Yerushalmi Database), and there are no known genizah fragments of this sugiya. This quotation is 376 words long, and includes both Mishnah Shabbat 7:2 and some of the Yerushalmi ad loc (Ed. Jerusalem, p. 404, ll. 25-50).
The Mishnah in the quotation displays a “mixed” text type. That the text type of the Mishnah here is not purely Palestinian shows that it was not originally part of a Yerushalmi manuscript, but was supplied later – either by the person who compiled the homilies in MS New York or by the copyist of the Yerushalmi MS used by the compiler. A similar phenomenon is apparent in MS Leiden itself, whose Mishnah may have been copied from MS Parma, as demonstrated by I. Z. Feintuch in 1976.
Like all other known Yerushalmi texts, the quotation offers essentially the same text found in MS Leiden as well as all the medieval authors who quote this text. Its value is in supplying corrections for the text found in MS Leiden, pointing out slight dialectical differences, and corroborating several readings added to MS Leiden by later readers. It also displays two corrupt readings which reflect a lack of knowledge with the Yerushalmi’s terminology and dialect. For example, where MS Leiden (p. 404, l. 25) explains that R. Ashian reported “the eyes of R. Aha went through the entire Torah and did not find that this thing was written” (אשגרת עיינה דר’ אחא בכל אוריתא ולא אשכח כת’ דא מילתא), the quotation reads that R. Ashian claims to have “closed the eyes of R. Aha every night” (אסגרת עיניה דר’ אחא בכל אורתא) and that he did not find this thing written. This reading makes little grammatical sense, and there is little apparent connection between the first and last clauses of the sentence. But the form אשגר עיניה was unfamiliar to a copyist, who emended it to something he understood (on this sentence, see Lieberman, Hayerushalmi Ki-fshuto, p. 128; Sokoloff, Dictionary of Jewish Palestinian Aramaic, p. 538a; Assis, Otzar Leshonot Yerushalmiyim, p. 170).
An interesting feature of the Yerushalmi text in the quotation is its agreement with emendations to MS Leiden. These agreements show us that at least some emendations to tractate Shabbat were based on other Manuscripts of Yerushalmi which we no longer have, and not on scholarly conjectures. This situation is similar to that of Order Zeraim which was emended according to MS Vatican 133, as demonstrated by E. Z. Melammed in 1981, and in accordance with the claims of the printers in the colophon to ed. Vienna.
For those interested, a longer form of this blog post is in the works.
