After the installation of Joshua, only one thing remained for Moses to do that all things might be set in order before his departure. This was the finishing of the writing of the Book of the Law, and the committing it finally to the priests, to be by them placed by the ark of the covenant, that it might be kept for all future generations as a witness against the people, whose apostasy and rebellion were foreseen.
Whether this section is to be regarded as wholly written by Moses himself, or as an appendix to his writing added by some other writer, has been made matter of question. It is quite possible, however, that Moses himself, ere he laid down the pen, may have recorded what he said when delivering the Book of the Law to the priests, and there is nothing in the manner or style of the record to render it probable that it was added by another. What follows from verse 30 to the end of the book was probably added to the writing of Moses by some one after his death, though, of course, both the song in Deuteronomy 32:1-52, and the blessing in Deuteronomy 33:1-29, are the composition of Moses (see Introduction, § 6).
