Abraham ibn Ezra
Rabbi Abraham Ben Meir Ibn Ezra (Hebrew: אברהם אבן עזרא or ראב"ע, Arabic ابن عزرا; also known as Abenezra) (1089–1164) was born at Tudela, Navarre (now in Spain) in 1089, and died c. 1167, apparently in Calahorra. He was one of the most distinguished Jewish men of letters and writers of the Middle Ages. Ibn Ezra excelled in philosophy, astronomy/astrology, mathematics, poetry, linguistics, and exegesis; he was called The Wise, The Great and The Admirable Doctor.
He was born at Tudela, (in the present-day province of Navarre) when the town was under the Muslim rule of the emirs of Zaragoza. Later he lived in Córdoba. In Granada, it is said, he met his future friend (and perhaps his father-in-law) Yehuda Halevi. He left Spain before 1140 to escape persecution of the Jews by the new fanatical regime of the Almohads. He led a life of restless wandering, which took him to North Africa, Egypt (in 1109, maybe in the company of Yehuda Halevi), the Land of Israel, Italy (Rome in 1140-1143, Lucca, Mantua, Verona), Southern France (Rodez, Narbonne, Béziers), Northern France (Dreux), England (London, and Oxford in 1158), and back again to Narbonne in 1161, until his death on January 23 or 28, 1167, the exact location unknown: maybe at Calahorra at the border of Navarre and Aragon, or maybe in Rome or in the Holy Land. There is a legend that he died in England from a fever and a sickness which came upon him after an encounter with a pack of wild black dogs. This legend is attached to the belief that he denied the existence of demons. 
At several of the above-named places, Ibn Ezra remained for some time and developed a rich literary activity. In his native land, he had already gained the reputation of a distinguished poet and thinker but apart from his poems, his works, which were all in the Hebrew language, were written in the second period of his life. With these works, which cover in the first instance the field of Hebrew philology and Biblical exegesis, he fulfilled the great mission of making accessible to the Jews of Christian Europe the treasures of knowledge enshrined in the works written in Arabic which he had brought with him from Spain.
His grammatical writings, among which Moznayim ("Scales", 1140) and Zahot (Tzahot = "Dazzlings", 1141) are the most valuable, were the first expositions of Hebrew grammar in the Hebrew language, in which the system of Judah Hayyuj and his school prevailed. He also translated into Hebrew the two writings of Hayyuj in which the foundations of the system were laid down.
Of greater original value than the grammatical works of Ibn Ezra are his commentaries on most of the books of the Bible, of which, however, the Books of Chronicles have been lost. His reputation as an intelligent and acute expounder of the Bible was founded on his commentary on the Pentateuch, of which the great popularity is evidenced by the numerous commentaries which were written upon it. In the editions of this commentary (editio princeps Naples 1488. See image at right), the commentary on the Book of Exodus is replaced by a second, more complete commentary of Ibn Ezra, while the first and shorter commentary on Exodus was not printed until 1840. The great editions of the Hebrew Bible with rabbinical commentaries contained also commentaries of Ibn Ezra's on the following books of the Bible: Isaiah, Minor Prophets, Psalms, Job, Pentateuch, Daniel; the commentaries on Proverbs, Ezra and Nehemiah which bear his name are really those of Moses Kimhi. Ibn Ezra wrote a second commentary on Genesis as he had done on Exodus, but this was never finished. There are second commentaries also by him on the Song of Songs, Esther and Daniel.
Ibn Ezra also wrote a commentary on the book of Ecclesiastes. Uncharacteristically of either Ibn Ezra's other commentaries on biblical works, or of Jewish exegesis of the time, the commentary on Ecclesiastes begins with an autobiographical poem (written in the third person) relating his life experience to the material in Ecclesiastes. Although the poem states that he fled "from [my] home in Spain/Going down to Rome with heavy spirit," this does not resolve the question of what intermediate journeys Ibn Ezra may have made before settling in Rome, possibly in the company of R' Yehudah HaLevi.
The importance of the exegesis of Ibn Ezra consists in the fact that it aims at arriving at the simple sense of the text, the Peshat, on grammatical principles. It is in this that, although he takes a great part of his exegetical material from his predecessors, the originality of his mind is everywhere apparent, an originality which displays itself also in the witty and lively language of his commentaries. Ibn Ezra is claimed by the proponents of the higher biblical criticism of the Pentateuch as one of its earliest pioneers. Baruch Spinoza, basing his opinion on verses cited by Ibn Ezra in the beginning of Deuteronomy, concludes that Moses did not author the Pentateuch and that the Pentateuch was written much later. Spinoza and later scholars were able to expand on several of Ibn Ezra's hints and provide much stronger evidence for Non-Mosaic authorship. Some Orthodox writers have recently addressed one of Ibn Ezra's hints that can be interpreted to be consistent with the Orthodox Jewish creed that the entire Pentateuch was divinely dictated in a word-perfect manner to Moses.
Ibn Ezra's commentaries, and especially some of the longer excursuses, contain numerous contributions to the philosophy of religion. One work in particular which belongs to this province, Yesod Mora ("Foundation of Awe"), on the division and the reasons for the Biblical commandments, he wrote in 1158 for a London friend, Joseph ben Jacob. In his philosophical thought neo-platonic ideas prevail; and astrology also had a place in his view of the world. He also wrote various works on mathematical and astronomical subjects, among which "three treatises on numbers which helped to bring the Indian symbols and ideas of decimal fractions to the attention of some of the learned people in Europe"
In his commentary, Ibn Ezra adheres to the literal sense of the texts, avoiding Rabbinic allegories and Cabbalistic interpretations, though he remains faithful to the Jewish traditions. This does not prevent him from exercising an independent criticism, which, according to some writers, borders on rationalism. In contrast his other works, the most important of which include The Book of the Secrets of the Law, The Mystery of the Form of the Letters, The Enigma of the Quiescent Letters, The Book of the Name, The Book of the Balance of the Sacred Language and The Book of Purity of the Language, demonstrate a more Cabbalistic viewpoint. They were written during his life of travel, and they reflect the unsteadiness of his outward circumstances.
The wandering life of an exile, such as Ibn Ezra led for nearly three decades, gave him the opportunity to carry out a mission which was to an eminent degree historical. He became a propagator among the Jews of Christian Europe, who were unacquainted with Arabic, of the study of Judaism, a science which had been founded long before with that language as its literary medium. He was fitted for this mission, as no one else, through the versatility of his learning and through his clear and charming Hebrew style. The great compass of his literary activity will be seen from the following résumé of his works.
His chief work is the commentary on the Torah, which, like that of Rashi, has called forth a host of super-commentaries, and which has done more than any other work to establish his reputation. It is extant both in numerous manuscripts and in printed editions. The commentary on Exodus published in the printed editions is a work by itself, which he finished in 1153 in southern France.
The complete commentary on the Pentateuch, which, as has already been mentioned, was finished by Ibn Ezra shortly before his death, was called Sefer ha-Yashar ("Book of the Straight").
In the rabbinical editions of the Bible the following commentaries of Ibn Ezra on Biblical books are likewise printed: Isaiah; the Twelve Minor Prophets; Psalms; Job; the Megillot; Daniel. The commentaries on Proverbs and Ezra-Nehemiah which bear Ibn Ezra's name are by Moses Kimhi. Another commentary on Proverbs, published in 1881 by Driver and in 1884 by Horowitz, is also erroneously ascribed to Ibn Ezra. Additional commentaries by Ibn Ezra to the following books are extant: Song of Solomon; Esther; Daniel. He also probably wrote commentaries to a part of the remaining books, as may be concluded from his own references..

Ibn Ezra composed his first book on astrology in Italy, before his move to France:
- Mishpetai ha-Mazzelot ("Judgments of the Zodiacal Signs"), on the general principles of astrology
In seven books written in Béziers in 1147–1148 Ibn Ezra then composed a systematic presentation of astrology, starting with an introduction and a book on general principles, and then five books on particular branches of the subject. The presentation appears to have been planned as an integrated whole, with cross-references throughout, including references to subsequent books in the future tense. Each of the books is known in two versions, so it seems that at some point Ibn Ezra also created a revised edition of the series.
