 Another of Judah's teachers was Nathan the Babylonian, who also took a part in the conflict between Meir and the patriarch; Judah confessed that once, in a fit of youthful ardor, he had failed to treat Nathan with due reverence.In both halakhic and aggadic tradition, Judah's opinion is often opposed to Nathan's.In the Palestinian tradition, Judah ben Korshai (the halakhic specialist mentioned as assistant to Simon ben Gamaliel) is designated as Judah's real teacher.
