4 and what he did to the army of Egypt, to their horses and to their chariots, how he made the water of the Red Sea flow over them as they pursued after you, and how the Lord has destroyed them to this day, 5 and what he did to you in the wilderness, until you came to this place, 6 and what he did to Dathan and Abiram the sons of Eliab, son of Reuben, how the earth opened its mouth and swallowed them up, with their households, their tents, and every living thing that followed them, in the midst of all Israel. 7 For your eyes have seen all the great work of the Lord that he did.

The Blessings of the Promised Land

8 "You shall therefore keep the whole commandment that I command you today, that you may be strong, and go in and take possession of the land that you are going over to possess, 9 and that you may live long in the land that the Lord swore to your fathers to give to them and to their offspring, a land flowing with milk and honey.

Matthew Henry's Commentary on Deuteronomy 11:4-9

Commentary on Deuteronomy 11:1-7

(Read Deuteronomy 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, 1 John 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.

Commentary on Deuteronomy 11:8-17

(Read Deuteronomy 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.
