R. Aaron ibn Hayyim (1545–1632), rabbi and commentator. Ibn Hayyim was born in Fez and studied at the yeshivot of his father, of R. Vidal ha-Zarefati, and of R. Joseph Almosnino. He was appointed a member of the bet din of Vidal in Fez, but in 1606 left for Egypt. In 1609 he went to Venice to publish his book, Korban Aharon (1609), and remained there at least three years. From there he traveled to the countries of the Orient and finally settled in Jerusalem, where he died. Among those who eulogized him were R. Azariah Figo and R. Leone Modena. Ibn Hayyim's fame rests on his commentaries to the Sitra (this lot), Mekhilta and the Sifrei, to the Pentateuch, the Prophets, and the Song of Songs, but only his Lev Aharon on Joshua and Judges, giving both the literal meaning and aggadic exposition, has been published (Venice, 1609). Some of his responsa appear in the works of his contemporaries.
