And Moses went and spake these words. By the word went he signifies that, having received the commands from God, he came to the people to report them. Hence we gather that they were warned in good time to beware, if they had been sensibly disposed. And it was necessary that the people should hear from his own mouth these addresses, which were by no means gratifying, as being full both of cruel threats and severe reproofs; for, if they had been delivered after his death, they would have straightway all exclaimed that they had been deceitfully devised by some one else, and thus that his name was falsely attached to them. Moreover, the peculiar time of their delivery did not a little avail to enhance their weight, so that the people should not only submit themselves with meekness and teachableness to his instruction at the moment, but also that it might remain hereafter deeply impressed upon their hearts. We know with what attention the last words of the dying are usually received; and Moses, now ready to meet death at God's command, addressed the people as if bidding them finally farewell. To the credit and dignity belonging to his office as a Prophet, there was consequently added all the force and authority of a testamentary disposition. As throughout his life he had been incredibly anxious for the people's welfare, so he now carries his more than paternal care still further. And assuredly it becomes all pious teachers to provide, as far as in them lies, that the fruit of their labors should survive them. Of this solicitude Peter sets himself before us as an example: "I think it meet (he says), as long as I am in this tabernacle, to stir you up by putting you in remembrance; moreover, I will endeavor that ye may be able after my decease to have these things always in remembrance." (2-Peter 1:13, 15)
And Moses went and spake these words unto all Israel. The following words, even to the whole body of the people summoned together on this occasion. It seems that after Moses had made the covenant with them he was directed to, he dismissed the people to their tents, and went to his own, and now returned, having ordered them to meet him again, very probably at the tabernacle; with which agrees the Targum of Jonathan, he"went to the tabernacle of the house of doctrine;''though, according to Aben Ezra, he went to the each tribes separately, as they lay encamped; his words are these,"he went to every tribe and tribe, to acquaint them that he was about to die, and that they might not be afraid, and to strengthen their hearts;''he adds,"in my opinion he then blessed them, though their blessings are afterwards written;''which is not improbable.
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, Hebrews 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.
MOSES ENCOURAGES THE PEOPLE AND JOSHUA. (Deuteronomy 31:1-8)
Moses went and spake--It is probable that this rehearsal of the law extended over several successive days; and it might be the last and most important day on which the return of Moses to the place of assembly is specially noticed. In drawing his discourse towards a conclusion, he adverted to his advanced age; and although neither his physical nor intellectual powers had suffered any decay (Deuteronomy 34:7), yet he knew, by a special revelation, that the time had arrived when he was about to be withdrawn from the superintendence and government of Israel.
Deuteronomy 31:1-13 describe how Moses promised the help of the Lord in the conquest of the land, both to the people generally, and also to Joshua, their leader into Canaan (Deuteronomy 31:2-8), and commanded the priests to keep the book of the law, and read it publicly every seventh year (Deuteronomy 31:9-13); and Deuteronomy 31:14-23, how the Lord appeared to Moses before the tabernacle, and directed him to compose an ode as a testimony against the apostasy of the people, and promised Joshua His assistance. And lastly, Deuteronomy 31:24-27 relate how the book of the law, when brought to completion, was handed over to the Levites; and Deuteronomy 31:28-30 describe the reading of the ode to the people.
Went and spake - Continued to speak, an usual Hebrew phrase.
