Moses Judah ben Meir Abbas (; âÂÂ1671), also known by the acronym Mashya (), was a 17th-century Talmudist and Hebrew poet.
Abbas was born in Salonika (back then part of the Ottoman Empire) into a prominent Sephardi literary family. He later settled in Egypt, where he founded a yeshiva and Talmud Torah, and, in the last years of his life, served as a rabbi in Rosetta. He left a commentary entitled Kisse kavod on the minor tractates Kallah, Soferim, and Semaḥot, and several responsa, which exist in manuscript form in the Bodleian collection.
