Deuteronomy (i.e. the Second Law), the fifth book of the Pentateuch, and so called as the re-statement and re-enforcement, as it were, by Moses of the Divine law proclaimed in the wilderness. The Mosaic authorship of this book is now called in question, though it is allowed to be instinct with the spirit of the religion instituted by Moses, and it is considered to have been conceived at a time when that religion with its ritual was established in Jerusalem, in order to confirm faith in the Divine origin and sanction of observances there.
