Deuteronomy 31

31:1-8 Moses assures Israel of the constant presence of God with them. This is applied by the apostle to all God's spiritual Israel, to encourage their faith and hope; unto us is this gospel preached, as well as unto them; he will never fail thee, nor forsake thee, Heb 13:5. Moses commends Joshua to them for a leader; one whose wisdom, and courage, and affection they had long known; one whom God had appointed to be their leader; and therefore would own and bless. Joshua is well pleased to be admonished by Moses to be strong and of good courage. Those shall speed well, who have God with them; therefore they ought to be of good courage. Through God let us do valiantly, for through him we shall do victoriously; if we resist the devil, he will flee from us.

Chapter 31 In this chapter Moses, having finished his sermon, I. Encourages both the people who were now to enter Canaan (v. 1-6), and Joshua who was to lead them (v. 7, 8, 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 (v. 9, and 24-27). (3.) Ordered to be publicly read every seventh year (v. 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 (v. 14, 15). (2.) He foretels the apostasy of Israel in process of time, and the judgments they would thereby bring upon themselves (v. 16–18). (3.) He prescribes the following song to be a witness against them (v. 19–21). (4.) Moses wrote it (v. 22). And delivered it to Israel, with an intimation of the design of it, as he had received it from the Lord (v. 28, etc.).Verses 1-8 Loth to part (we say) bids oft farewell. Moses does so to the children of Israel: not because he was loth to go to God, but because he was loth to leave them, fearing that when he had left them they would leave God. He had finished what he had to say to them by way of counsel and exhortation: here he calls them together to give them a word of encouragement, especially with reference to the wars of Canaan, in which they were now to engage. It was a discouragement to them that Moses was to be removed at a time when he could so ill be spared: though Joshua was continued to fight for them in the valley, they would want Moses to intercede for them on the hill, as he did, Ex. 17:10. But there is no remedy: Moses can no more go out and come in, v. 2. Not that he was disabled by any decay either of body or mind; for his natural force was not abated, ch. 24:7. But he cannot any longer discharge his office; for, 1. He is 120 years old, and it is time for him to think of resigning his honour and returning to his rest. He that had arrived at so great an age then, when seventy or eighty was the ordinary stint, as appears by the prayer of Moses (Ps. 90:10), might well think that he had accomplished as a hireling his day. 2. He is under a divine sentence: Thou shalt not go over Jordan. Thus a full stop was put to his usefulness; hitherto he must go, hitherto he must serve, but no further. So God had appointed it and Moses acquiesces: for I know not why we should any of us desire to live a day longer than while God has work for us to do; nor shall we be accountable for more time than is allotted us. But, though Moses must not go over himself, he is anxious to encourage those that must.I. He encourages the people; and never could any general animate his soldiers upon such good grounds as those on which Moses here encourages Israel. 1. He assures them of the constant presence of God with them (v. 3): The Lord thy God. that has led thee and kept thee hitherto will go over before thee; and those might follow boldly who were sure that they had God for their leader. He repeats it again (v. 6) with an emphasis: "The Lord thy God, the great Jehovah, who is thine in covenant, he it is, he and no less, he and no other, that goes before thee; not only who by his promise has assured thee that he will go before thee; but by his ark, the visible token of his presence, shows thee that he does actually go before thee." And he repeats it with enlargement: "Not only he goes over before thee at first, to bring thee in, but he will continue with thee all along, with thee and thine; he will not fail thee nor forsake thee; he will not disappoint thy expectations in any strait, nor will he ever desert thy interest; be constant to him, and he will be so to thee." This is applied by the apostle to all God’s spiritual Israel, for the encouragement of their faith and hope; unto us is this gospel preached, as well as unto them He will never fail thee, nor forsake thee, Heb. 13:5. 2. He commends Joshua to them for a leader: Joshua, he shall go over before thee, v. 3. One whose conduct, and courage, and sincere affection to their interest, they had had long experience of; and one whom God had ordained and appointed to be their leader, and therefore, no doubt, would own and bless, and make a blessing to them. See Num. 27:18. Note, It is a great encouragement to a people when, instead of some useful instruments that are removed, God raises up others to carry on his work. 3. He ensures their success. The greatest generals, supported with the greatest advantages, must yet own the issues of war to be doubtful and uncertain; the battle is not always to the strong nor to the bold; an ill accident unthought of may turn the scale against the highest hopes. But Moses had warrant from God to assure Israel that, notwithstanding the disadvantages they laboured under, they should certainly be victorious. A coward will fight when he is sure to be a conqueror. God undertakes to do the work—he will destroy these nations; and Israel shall do little else than divide the spoil—thou shalt possess them, v. 3. Two things might encourage their hopes of this:—(1.) The victories they had already obtained over Sihon and Og (v.
