The commentary of Rabbi Joseph Hayyun, who was one of the greatest rabbis of Portugal in the generation before the deportation, to Jeremiah, has remained since its composition only in manuscript and did not reach the printing press. In this edition, an effort was made to invent for those seeking biblical interpretation, an illustrated scientific edition of the commentary, from the only surviving manuscript, which is apparently an autograph that Rabbi Hayyun repeatedly proofread several times. At the beginning of the book is a comprehensive introduction, which discusses Rabbi Hayon's interpretive way as it is reflected in his commentary on Jeremiah, various matters arising from his commentary concerning the book of Jeremiah, and matters of faith and philosophy mentioned during the commentary.
