Joseph ben Hayyim Jabez (also "Yaavetz") (1438 – 1539)[1] was a Spanish-Jewish theologian.
He lived for a time in Portugal, where he associated with Joseph ben Abraham Ḥayyun, who inspired him with that taste for mysticism which he subsequently displayed in his writings.
For him, the truth of religion is demonstrated by the miracles recorded in the Hebrew Bible.
He criticizes the thirteen articles of faith of Maimonides, the six of Hasdai Crescas, and the three of Joseph Albo.
According to him, only the following three, alluded to in the verse about "I Am that I Am" in the narrative of the burning bush in the Book of Exodus, are the fundamental principles of Judaism: These dogmas are expounded by him in the following books: Jabez left also a great number of manuscript works, which, according to Ghirondi, are still (as of 1906) in the possession of the author's descendants.
