The Most Important Books of the Bible - Deuteronomy

The founders of the United States cited deuteronomy more than any other book in their writings and in their speaking, even more than enlightenment thinkers like montesquieu. "I've devoted a big chunk of time to thinking about it. I'm just trying to do what i'm supposed to do," says author Elizabeth Warren. The first five books of the bible are known as the 'tora', or rational bible.
