Lyric discussion by brimah87 

I think that the book Bob is referring to is a supposed lost, second part of the Bible. Basically what it boils down to is that Rastas believe that Ethiopians are descendents of the exiled people of Isreal, and that the coronation of Haile Selassie was predicted in the Bible, and that he is Jesus reincarnated (there is a lot of cool stuff you can read about how they justify this, Google "Lion of Judah" and "Rastafari" to get a better sense of it, I am no expert I'm just giving the gist of it). They believe that among the exiled peoples of Isreal, one of the tribes carried the Arc of the Covenant. According to Rastas, in the Arc of the Covenant is an additional holy book which contains a wealth of African-specific wisdom and spiritual truth.

I've read quite a few comments that claim that Bob was anti-religious. This is so false, he was not only spiritual but extremely religious: a complete zealot of Rastafari. Ratsafarians believe that over history and through many translations that the Bible has been corrupted and anglicized, changed to marginalize Africans and pander to Europeans. They contend that since we know the human species originated in Africa, that Adam and Eve were Africans, and the Garden of Eden and Mount Zion must be in Africa. So when Bob denounces religion (which he does do pretty often, like in "Get Up, Stand Up") he is criticizing the modern, white-washed version of Christianity.

I don't really know how this all fits into the whole song, but I am pretty sure that the book is a lost portion of the bible. I think that "We've got to fulfill the book" is an argument AGAINST "Some say it's just a part of it". In other words, I think he is saying that Africans shouldn't just accept oppression as a part of life, but that they should live up to the ideals of the true message of the bible, a message that has been diluted and corrupted over the course of human history.
