On this side Jordan, in the land of Moab. — This would be on the other side of Jordan from the stand-point of the writer, or of the readers for whom the book was intended, which is Palestine.
Began Moses. — “Began,” i.e., “determined” or “assayed.”
To declare. — The emphatic reiteration of what had been already received from God and delivered to Israel may be intended. But the Hebrew word here employed occurs in two other places only, and in both is connected with writing. (See Deuteronomy 17:8, “thou shalt write upon the stones all the words of this law very plainly” (bâêr hêtêb, in writing and in making good). Again, in Habakkuk 2:2, “write the vision, and make it plain upon tables.” The etymological affinities of the word also suggest the idea of writing. It would seem, then, that at this period Moses began to throw the discourses and laws that he had delivered into a permanent form, arranging and writing them with the same motive which influenced the Apostle Peter (2 Peter 1:15), “Moreover, I will endeavour that ye may be able after my decease to have these things always in remembrance.”
In this discourse the history of Israel, from the time of their departure from Sinai, is briefly recapitulated (Deuteronomy 3:29), and with a short practical exhortation. This portion of history comprises three periods of the exodus: (1) The march from Sinai to Kadesh-barnea, with the sending of the twelve spies and its results, related more at length in Numbers 10:11 — end of Deuteronomy 14. The characteristic feature of this period is failure on the part of both leaders and people to rise to their high calling. Moses (Numbers 11), Aaron and Miriam (Num. xii), Joshua (Numbers 11:28), the spies, who were also rulers (Deuteronomy 13:14), and the people throughout, all in turn exhibit the defects of their character. In the end the enterprise is abandoned for the time. (2) The thirty seven and a half years that follow are a period of disgrace, as appears by the absence of all note of time or place in the direct narrative between Numbers 14 and Numbers 20. Certain places are mentioned in Numbers 33 which must belong to this period, but nothing is recorded of them beyond the names. A single verse (Deuteronomy 2:1), is all that is assignable to that period in this discourse of Moses. This long wandering was also a period of training and discipline. (3) The fortieth year of the exodus, in which the conquest of Sihon and Og was effected, and Israel reached the banks of Jordan. The sentence of death pronounced against their elder generation having been executed, a new life was now begun.
