All the commandments which I command thee this day shall ye observe (a) to do, that ye may live, and multiply, and go in and possess the land which the LORD sware unto your fathers.
(a) Showing that it is not enough to hear the word, unless we express it by the example of our lives.
All the commandments which I command thee this day shall ye observe to do,.... It is repeated over and over again, to impress it on their minds, and to show the importance and necessity of it, how greatly it was expected from them, and how much it was incumbent on them:
that ye may live and multiply, and go in and possess the land which the Lord sware unto your fathers; for their temporal life, and the mercies and comforts of it, the multiplication of their offspring, and of their substance, their entrance into the land of Canaan, possession of it, and continuance in it, all depended on their obedience to the commands of God; see Deuteronomy 19:20.
Obedience must be, 1. Careful, observe to do; 2. Universal, to do all the commandments; and 3. From a good principle, with a regard to God as the Lord, and their God, and with a holy fear of him. To engage them to this obedience. Moses directs them to look back. It is good to remember all the ways, both of God's providence and grace, by which he has led us through this wilderness, that we may cheerfully serve him and trust in him. They must remember the straits they were sometimes brought into, for mortifying their pride, and manifesting their perverseness; to prove them, that they and others might know all that was in their heart, and that all might see that God chose them, not for any thing in them which might recommend them to his favour. They must remember the miraculous supplies of food and raiment granted them. Let none of God's children distrust their Father, nor take any sinful course for the supply of their necessities. Some way or other, God will provide for them in the way of duty and honest diligence, and verily they shall be fed. It may be applied spiritually; the word of God is the food of the soul. Christ is the word of God; by him we live. They must also remember the rebukes they had been under, and not without need. This use we should make of all our afflictions; by them let us be quickened to our duty. Moses also directs them to look forward to Canaan. Look which way we will, both to look back and to look forward, to Canaan. Look which way we will, both to look back and to look forward will furnish us with arguments for obedience. Moses saw in that land a type of the better country. The gospel church is the New Testament Canaan, watered with the Spirit in his gifts and graces, planted with trees of righteousness, bearing fruits of righteousness. Heaven is the good land, in which nothing is wanting, and where is fulness of joy.
AN EXHORTATION TO OBEDIENCE. (Deuteronomy. 8:1-20)
All the commandments which I command thee this day shall ye observe to do, that ye may live--In all the wise arrangements of our Creator duty has been made inseparably connected with happiness; and the earnest enforcement of the divine law which Moses was making to the Israelites was in order to secure their being a happy (because a moral and religious) people: a course of prosperity is often called "life" (Genesis 17:18; Proverbs 3:2).
live, and multiply--This reference to the future increase of their population proves that they were too few to occupy the land fully at first.
In addition to the danger of being drawn aside to transgress the covenant, by sparing the Canaanites and their idols out of pusillanimous compassion and false tolerance, the Israelites would be especially in danger, after their settlement in Canaan, of falling into pride and forgetfulness of God, when enjoying the abundant productions of that land. To guard against this danger, Moses set before them how the Lord had sought to lead and train them to obedience by temptations and humiliations during their journey through the desert. In order that his purpose in doing this might be clearly seen, he commenced (Deuteronomy 8:1) with the renewed admonition to keep the whole law which he commanded them that day, that they might live and multiply and attain to the possession of the promised land (cf. Deuteronomy 4:1; Deuteronomy 6:3).
Live - Live comfortably and happily.
