Deuteronomy 31:21

IV. Moses' Farewell and Death - Deuteronomy 31-34 With the renewal of the covenant, by the choice set before the people between blessing and curse, life and death, Moses had finished the interpretation and enforcement of the law (Deu 1:5), and brought the work of legislation to a close. But in order that the work to which the Lord had called him might be thoroughly completed, it still remained for him, before his approaching death, to hand over the task of leading the people into Canaan to Joshua, who had been appointed as his successor, to finish writing out the laws, and to hand over the book of the law to the priests. The Lord also directed him to write an ode, as a witness against the people, on account of their obstinacy, and teach it to the Israelites. To these last arrangements and acts of Moses, which are narrated in ch. 31 and 32, there are added in ch. 33 the blessing with which this man of god bade farewell to the tribes of Israel, and in ch. 34 the account of his death, with which the Pentateuch closes.

In this chapter Moses, having finished his sermon, I. Encourages both the people who were now to enter Canaan (Deu 31:1-6), and Joshua who was to lead them (Deu 31:7, Deu 31:8, Deu 31:23). And, II. He takes care for the keeping of these things always in their remembrance after his decease, 1. By the book of the law which was, (1.) Written. (2.) Delivered into the custody of the priests (Deu 31:9, and Deu 31:24-27). (3.) Ordered to be publicly read every seventh year (Deu 31:10-13). 2. By a song which God orders Moses to prepare for their instruction and admonition. (1.) He calls Moses and Joshua to the door of the tabernacle (Deu 31:14, Deu 31:15). (2.) He foretels the apostasy of Israel in process of time, and the judgments they would thereby bring upon themselves (Deu 31:16-18). (3.) He prescribes the following song to be a witness against them (Deu 31:19-21). (4.) Moses wrote it (Deu 31:22). And delivered it to Israel, with an intimation of the design of it, as he had received it from the Lord (Deu 31:28, etc.).
