Johanan is frequently mentioned in the Talmud of Jerusalem in connection with both halakic and haggadic subjects, instances of the latter, however, predominating. In a controversy between R. Mana and R. Hananiah as to whether any high place may temporarily be used by a prophet as an altar, Johanan used Joshua 8:30 and 1 Samuel 7:9 to support the affirmative opinion of Hananiah (Yer. Meg. 1:14; Lev. R. 22:6; Midr. Teh. to Psalms 27:6, where the name "Jacob" occurs). He also transmitted a haggadah of Johanan b. Nappaḥa (Yer. Peah 1:1).
