Or the repetition of the law, the fifth book of the Pentateuch, so called by the Greeks, because in it Moses recapitulates what he had ordained in the preceding books, Deuteronomy 1:1-6 29:1 31:1 33:1-29. This book contains the history of what passed in the wilderness from the beginning of the eleventh month, to the seventh day of the twelfth month, in the fortieth year after the Israelites’ departure from Egypt, that is, about six weeks, B. C. 1451. That part which mentions the death of Moses was added afterwards, very probably by Joshua.
The book of Deuteronomy is the sublime and precious valedictory address of the inspired "man of God," now venerable for his age and experience, and standing almost in the gate of heaven. He gives the people of God his fatherly counsel and blessing, and then goes up into mount Pisgah alone to die. He recounts the dealings of God with them; recapitulates his laws; shows them why they should love him, and how they should serve him. It is full of tender solicitude, wise instruction, faithful warning, and the zealous love of a patriot and a prophet for the people of God, whom he had borne on his heart so long. It is often quoted by later inspired writers, and by our Lord, Matthew 4:4,7,10.
