Deuteronomy 31:9-13

Verse 9

Moses wrote this law - Not the whole Pentateuch, but either the discourses and precepts mentioned in the preceding chapters, or the book of Deuteronomy, which is most likely.

Some of the rabbins have pretended that Moses wrote thirteen copies of the whole Pentateuch; that he gave one to each of the twelve tribes, and the thirteenth was laid up by the ark. This opinion deserves little credit. Some think that he wrote two copies, one of which he gave to the priests and Levites for general use, according to what is said in this verse, the other to be laid up beside the ark as a standard copy for reference, and to be a witness against the people should they break it or become idolatrous. This second copy is supposed to be intended Deu 31:26. As the law was properly a covenant or contract between God and the people, it is natural to suppose there were two copies of it, that each of the contracting parties might have one: therefore one was laid up beside the ark, this was the Lord's copy; another was given to the priests and Levites, this was the people's copy.
Verse 10

At the end of every seven years - thou shalt read this law - Every seventh year was a year of release, Deu 15:1, at which time the people's minds, being under a peculiar degree of solemnity, were better disposed to hear and profit by the words of God. I suppose on this ground also that the whole book of Deuteronomy is meant, as it alone contains an epitome of the whole Pentateuch. And in this way some of the chief Jewish rabbins understand this place.

It is strange that this commandment, relative to a public reading of the law every seven years, should have been rarely attended to. It does not appear that from the time mentioned Jos 8:30, at which time this public reading first took place, till the reign of Jehoshaphat 2Chr 17:7, there was any public seventh year reading - a period of 530 years. The next seventh year reading was not till the eighteenth year of the reign of Josiah, 2Chr 34:30, a space of two hundred and eighty-two years. Nor do we find any other publicly mentioned from this time till the return from the Babylonish captivity, Neh 8:2. Nor is there any other on record from that time to the destruction of Jerusalem.
