Rav Isaac bar Rav Judah (Hebrew: רב יצחק בריה דרב יהודה) was a Babylonian rabbi who lived in the 4th century (fourth generation of amoraim).
Biography
[edit]His father and principle teacher was Rav Judah ben Ezekiel, who was probably quite old when Isaac was born.[1] In his childhood Isaac already showed signs of unusual intelligence.[2] Isaac and his father debated many halakhic issues together.[3] His father regarded him highly, and would repeat teachings in his son's name, which was considered unusual, since usually the student would quote the teacher and not the reverse.[4] At times he would comment on his father's work.[5]
Isaac did not marry until a late age, because his father Judah did not know how to find a family with sufficiently good lineage, until Ulla visited and taught Judah a method for estimating lineage.[6] Isaac studied also under Rav Huna,[7] as well as under Rabbah bar Nahmani along with Rav Samuel, the son of Rabbah bar bar Hana, and Aha bar Hana.[8]
After their deaths, he became a student of Rami bar Hama. However, he did not like Rami's reliance on logical argumentation rather than reference to tradition,[9] and so he left Rami's lectures, to study under Rav Sheshet who would answer questions based on previous sources.[10]
Along with his brother, Huna bar Judah,[11] he debated halacha with Abaye and Rava.[12]
His family
[edit]His granddaughter Homa, the daughter of his son Issi, was termed Isha katlanit ("lethal/deadly woman"), since she married three men, all of whom died: Rehaba of Pumbeditha, Rab Isaac, the son of Rabbah bar bar Hana, and Abaye.[13]
