Verse 22. "Written in the story" - ¨rdmb 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.
