List three Old Testament books that contain no poetry sections?

I'm not exactly sure what you mean by 'Poetry sections'. Psalms is the only book that really was written in poetic form. And that's because it's actually a collection of songs. Thus the name 'Psalms'. So I've picked a few books which I believe have no or few poetic style scriptures in them: Genesis, Exodus, Hosea, Joel, Amos, Obadiah, Jonah, Micah, etc.

It might help to list the books that are generally placed in the poetry section: Job, Psalms, Proverbs, Ecclesiastes, Song of Songs.
