And the rest of the acts of Abijah, and his ways and his sayings, are recorded in the account of the prophet Iddo.

Now the rest of the words of Abijah, and his ways and works, have been written very diligently in the book of Iddo, the prophet.

Written in the story - במדרש bemidrash, "in the commentary;" this, as far as I recollect, is the first place where a midrash or commentary is mentioned. The margin is right.
His ways, and his sayings - The commentary of the prophet Iddo is lost. What his sayings were we cannot tell; but from the specimen in this chapter, he appears to have been a very able speaker, and one who knew well how to make the best use of his argument.

And the rest of the acts of Abijah, and his ways, and his sayings,.... Not only his warlike actions, and his course of life, but some remarkable sayings of his, he being a man of wisdom and eloquence, as his above speech shows:
are written in the story of the prophet Iddo; who might write the history of his own times; see 1-Kings 15:7.

As to the מדרשׁ of the prophet Iddo, see the Introduction.
13:23 (2-Chronicles 14:1). This is remarked here, because this rest was also a result of Abijah's great victory over Jeroboam.
