Italian Biblical commentator lived at Rome in the tenth century. Yir'am was styled "of Magdiel " in conformity with the rabbinical interpretation which refers the name "Magdiel" (Genesis 36:43 ) to Rome (comp. Rashi ad loc. ). He was a junior contemporary and perhaps also a pupil of Saadia, and was the author of a commentary on Chronicles, some fragments of which were united by a compiler with writings of other commentators, among them Judah ibn Ḳuraish, the whole being edited by Kirchheim under the title "Ein Kommentar zur Chronik aus dem 10. Jahrhundert" (Frankfort-on-the-Main, 1874). There are extant only three fragments of Yir'am's commentary: the first is taken from Saadia's commentary the second is a haggadic explanation of certain words and the third is an interpretation of the subject-matter, as to which Yir'am is charged by the compiler with not having thoroughly penetrated into the meaning of the passage.
