And {a} know ye this day: for I speak not with your children which have not known, and which have not seen the chastisement of the LORD your God, his greatness, his mighty hand, and his stretched out arm,

(a) You who have seen God's graces with your eyes should be moved, rather than your children who have only heard of them.

Wesley's Notes

11:2 Know - That is, acknowledge and consider it with diligence and thankfulness.

Jamieson-Fausset-Brown Bible Commentary

2-9. I speak not with your children which have not known . But your eyes have seen all the great acts of the Lord which he did-Moses is here giving a brief summary of the marvels and miracles of awful judgment which God had wrought in effecting their release from the tyranny of Pharaoh, as well as those which had taken place in the wilderness. He knew that he might dwell upon these, for he was addressing many who had been witnesses of those appalling incidents. For it will be remembered that the divine threatening that they should die in the wilderness, and its execution, extended only to males from twenty years and upward, who were able to go forth to war. No males under twenty years of age, no females, and none of the tribe of Levi, were objects of the denunciation (see Nu 14:28-30; 16:49). There might, therefore, have been many thousands of the Israelites at that time of whom Moses could say, "Your eyes have seen all the great acts which He did"; and with regard to those the historic review of Moses was well calculated to stir up their minds to the duty and advantages of obedience.

Matthew Henry's Concise Commentary

11:1-7 Observe the connexion of these two; Thou shalt love the Lord, and keep his charge. Love will work in obedience, and that only is acceptable obedience which flows from a principle of love, 1Jo 5:3. Moses recounts some of the great and terrible works of God which their eyes had seen. What our eyes have seen, especially in our early days, should affect us, and make us better long afterwards.

Matthew Henry's Whole Bible Commentary

Chapter 11

With this chapter Moses concludes his preface to the repetition of the statutes and judgments which they must observe to do. He repeats the general charge (v. 1), and, having in the close of the foregoing chapter begun to mention the great things God had done among them, in this, I. He specifies several of the great works God had done before their eyes (v. 2-7). II. He sets before them, for the future, life and death, the blessing and the curse, according as they did, or did not, keep God's commandments, that they should certainly prosper if they were obedient, should be blessed with plenty of all good things (v. 8-15), and with victory over their enemies, and the enlargement of their coast thereby (v. 22-25). But their disobedience would undoubtedly be their ruin (v. 16, 17). III. He directs them what means to use that they might keep in mind the law of God (v. 18-21). And, IV. Concludes all with solemnly charging them to choose which they would have, the blessing or the curse (v. 26, etc.).

Verses 1-7

Because God has made thee as the stars of heaven for multitude (so the preceding chapter concludes), therefore thou shalt love the Lord thy God (so this begins). Those whom God has built up into families, whose beginning was small, but whose latter end greatly increases, should use that as an argument with themselves why they should serve God. Thou shalt keep his charge, that is, the oracles of his word and ordinances of his worship, with which they were entrusted and for which they were accountable. It is a phrase often used concerning the office of the priests and Levites, for all Israel was a kingdom of priests, a holy nation. Observe the connection of these two: Thou shalt love the Lord and keep his charge, since love will work in obedience, and that only is acceptable obedience which flows from a principle of love. 1 Jn. 5:3.

Mention is made of the great and terrible works of God which their eyes had seen, v. 7. This part of his discourse Moses addresses to the seniors among the people, the elders in age; and probably the elders in office were so, and were now his immediate auditors: there were some among them that could remember their deliverance out of Egypt, all above fifty, and to them he speaks this, not to the children, who knew it by hearsay only, v. 2. Note, God's mercies to us when we were young we should remember and retain the impressions of when we are old; what our eyes have seen, especially in our early days, has affected us, and should be improved by us long after. They had seen what terrible judgments God had executed upon the enemies of Israel's peace, 1. Upon Pharaoh and the Egyptians that enslaved them. What a fine country was ruined and laid waste by one plague after another, to force Israel's enlargement! v. 3. What a fine army was entirely drowned in the Red Sea, to prevent Israel's being re-enslaved! v. 4. Thus did he give Egypt for their ransom, Isa. 43:3. Rather shall that famous kingdom be destroyed than that Israel shall not be delivered. 2. Upon Dathan and Abiram that embroiled them. Remember what he did in the wilderness (v. 5), by how many necessary chastisements (as they are called, v. 2) they were kept from ruining themselves, particularly when those daring Reubenites defied the authority of Moses and headed a dangerous rebellion against God himself, which threatened the ruin of a whole nation, and might have ended in that if the divine power had not immediately crushed the rebellion by burying the rebels alive, them and all that was in their possession, v. 6. What was done against them, though misinterpreted by the disaffected party (Num. 16:41), was really done in mercy to Israel. To be saved from the mischiefs of insurrections at home is as great a kindness to a people, and therefore lays them under as strong obligations, as protection from the invasion of enemies abroad.
