Joshua 23:6

Be ye therefore very courageous. The original is stronger, Be ye exceedingly courageous (see note on Joshua 1:6 ). That is written in the book of the law of Moses. A yet more distinct intimation that the words of Moses had been collected into a book at this early period, and that it was known as the Book of the Law of Moses. It seems incredible that such a book should have been invented at a time when the precepts it contained were lightly regarded, and should have been represented as the proper standard of conduct when every one knew that it could never have been anything of the kind.
