11:8-17 Moses sets before them, for the future, life and death, the blessing and the curse, according as they did or did not keep God's commandment. Sin tends to shorten the days of all men, and to shorten the days of a people's prosperity. God will bless them with an abundance of all good things, if they would love him and serve him. Godliness has the promise of the life that now is; but the favour of God shall put gladness into the heart, more than the increase of corn, and wine, and oil. Revolt from God to idols would certainly be their ruin. Take heed that your hearts be not deceived. All who forsake God to set their affection upon any creature, will find themselves wretchedly deceived, to their own destruction; and this will make it worse, that it was for want of taking heed.
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.
