Pinsker, but was lost during the Crimean war. He wrote also a short commentary on the Earlier Prophets, a fragment of which, covering the first ten chapters of Joshua, still exists (Brit. Mus. Or. No. 308). Steinschneider believes it possible that Levi was also the author of the short commentary on Psalms found in the British Museum (No. 336). According to Ali ben Sulaiman, Levi made a compendium of the lexicon "Agron" of David ben Abraham; however, this is contested by Abu al-Faraj, who asserts that the compendium was prepared by David himself.
