דברי הימים ב י״ב:ט״ו-ט״ז

בדברי שמעיה הנביא. כל נביא ונביא היה כותב ספרו מה שהיה מתנבא וזהו שמעיה שאמר לעיל (ב' י"א) ולקמן (י"ב) מוכיח ויתר דברי אביה ודרכיו ודבריו כתובין במדרש הנביא עדו ספרו היה נקרא מדרש:

in the words of Shemaiah the prophet Every prophet would write his book, containing that which he prophesied, and this is the Shemaiah who was mentioned above (11:2, 12:5). And the verse written further (13:22), “And the rest of the deeds of Abijah and his ways and his words are written in the midrash of the prophet Iddo,” proves this, [that each prophet wrote a book of his prophecies, and] his [Iddo’s] book was called midrash.
