Elder Bruce R. McConkie offered his opinion about the worth of some of the books of the Bible:
In the Old Testament, Genesis is the book of books – a divine account whose worth cannot be measured. Exodus and Deuteronomy are also of surpassing worth. Numbers, Joshua, Judges, the Samuels, the Kings, and the Chronicles are all essential history. Leviticus has no especial application to us. Ruth and Esther are lovely stories. The Psalms contain marvelous poetry and the portions that are messianic and that speak of the last days and the Second Coming are of great import. Proverbs, Ecclesiastes, and Lamentations are interesting books; Job is for people who like the book of Job; and the Song of Solomon is biblical trash – it is not inspired writing. …all the rest of the prophets – Isaiah above them all – each in his place and order set forth the doctrinal and prophetic word that must be studied in depth.
