Shmuel ben Meir (Rashbam) was a French Tosafist and Torah commentator. He was a son of Rashi's daughter, Yocheved, and older brother of the famous Tosafists, Isaac ben Meir (Rivam) and Jacob ben Meir (Rabbeinu Tam). His Torah commentary is concise, and hews strictly to the concept of the "peshat" or plain-sense meaning of the text, sometimes at the expense of received rabbinic traditions. He does not hesitate to argue with Rashi when he feels that his commentary strayed from the plain meaning of the verse.

Avraham ben Meir ibn Ezra, better known simply as Ibn Ezra, was a medieval Spanish Torah commentator, poet, philosopher and grammarian. While he wrote on grammar, philosophy, astronomy, medicine, and mathematics, he is most famous for his Biblical commentaries, which, along side those of Rashi, are ubiquitous and indipsensible. His commentaries focus on grammatical explanations and the "peshat" (plain-sense) meaning of the text. He often incorporates biting or humorous comments directed toward other commentators, especially towards the Karaites. He maintained a deep friendship with R. Yehudah Halevi, and quotes some of his interpretations in his commentaries. His poetry is still read and sung as part of the regular liturgy. Ibn Ezra knew great poverty and traveled widely, almost incessantly, teaching and making connections with fellow scholars, notably Rabbenu Tam in France.

Ovadiah ben Ya'akov Seforno was an Italian rabbi, Biblical commentator, philosopher, halachic authority, and physician who wrote commentaries on a good portion of the Tanach. After an early period of wandering, he settled in Bologna, where he founded a yeshiva. Sforno was held in high regard by his contemporaries, Maharam Padua and Maharik Kolon and is also quoted in responsa of contemporary authorities who consulted him on issues of Halacha. Seforno was admired for his wide knowledge by Henry II, King of France, to whom he sent a Latin translation he prepared of his philosophical work, Or Amim.

Shlomo ben Yitzhak, best known by the acronym "Rashi", was an early and influential medieval Torah and Talmud commentator. He was born in Troyes, France, and as a young man he studied in the yeshivot of Worms and Mainz. At the age of twenty-five he returned to Troyes and opened his own yeshiva. He supported his family and his yeshiva by growing grapes and producing and selling wine.Widely known as the father of all commentators, his commentary on the Bible and Talmud is considered an indispensable tool for Torah study. He described his aim as clarifying the "peshat" or "plain-sense" meaning of each verse. He was also a posek who authored responsa.

Don Yitzchak Abarbanel, often refered to simply as Abarbanel, was a Bible commentator, philosopher, apologist, financier and statesman. Born in Portugal, he displayed a great mastery of both Jewish and secular learning from his youth. His precocious abilities in financial matters attracted the attention of King Alfonso V of Portugal, who appointed him royal treasurer. He used his great wealth and position to help free Jews sold into slavery in Morocco. When Alfonso died in 1483 and Abarbanel was falsely accused of conspiring against the king, he fled for his life to Toledo in Castille, leaving behind a large fortune which had been confiscated. There he devoted himself to composing his famous Biblical commentary. He also answered the call of Queen Isabella and contracted as supplier of the royal army and tax farmer, lending significant sums to help fund the Moorish war. When the Edict of Expulsion was issued, he strove mightily to have it rescinded, offering a forture to the crown to no avail. He left with his brethern and settled in Naples. When that city was overtaken by the French, he again was forced to leave without his possessions, following his patron to Sicily, Corfu, and finally, to Venice. His apologetic works argued for the Jewish idea of the Mashiach, his exegetical works were unique in that they took social and political issues into consideration, and in his philosophical works he several criticisizes many of his Jewish philosophical predecessors.
