Now the acts of Rehoboam, first and last, are they not written in the histories of Shemaiah the prophet and of Iddo the seer, after the manner of genealogies? And there were wars between Rehoboam and Jeroboam continually.
Jerusalem Talmud Sanhedrin
“And one who disregards the prophet’s words.” Like the seer Ido98The text is lacunary. One must read with the Tosephta (14:15) and the Babli (89b): One who disregards the prophet’s words, like the companion of Micha (1K.20:35) and the prophet who disregards his own words like the seer Ido (mentioned in 2Chr. 12:15 who in all talmudic sources is identified as the anonymous “prophet from Jehudah” in 1K. 13). R. Samuel bar Rav Isaac said, the old prophet living in Bethel (1K. 13:11) is Amasiah the priest of Bethel (Am. 7:12).. Rebbi Samuel bar Rav Isaac said, this is Amaṣiah the priest of Bethel. Rebbi Yose said, this is breaking of eggs99R. Samuel bar Rav Isaac spoke in error; the old prophet at the time of Jeroboam I cannot be the priest at the time of Jeroboam II.; who is it? He is Jonathan ben Gershom ben Manasse100Jonathan ben Gershom ben Moses, as asserted in an anonymous note (Berakhot 9:3, Note 135). To support this assertion, the next paragraph is a rearrangement of a text in Berakhot 9:3 (Notes 128–135); it lacks the punch line that Jonathan was the old prophet..
