Claim: Nachum Ish Gamzu was the teacher of Rabbi Akiva, and taught him the exegetical principle of inclusion and exclusion and he is known by interpreting the whole Torah according to the rule of "ribbui u-mi'uṭ".
Evidence: Nachum was the teacher of Rabbi Akiva, and taught him the exegetical principle of inclusion and exclusion ("ribbui u-mi'uá¹­"). Only one halakhah of his has been preserved; but it is known that he interpreted the whole Torah according to the rule of "ribbui u-mi'uá¹­".
