(5) That ye should do so in the land.--It should never be forgotten that there is a special connection between the law of Moses and the land of Canaan. It cannot be kept in many of its precepts, except by a chosen people in a protected land.

Verses 5, 6. - The institutes of Moses were the commandments of Jehovah, and therefore obedience to them was imperative. By this was conditioned the enjoyment by Israel of the Promised Land; and this would be their wisdom and understanding in the sight of the nations; to themselves it would be life, and to the nations it would convey an impression of their being the depositories of true wisdom and knowledge, so that they should be constrained to say, Surely a wise and understanding people is this great nation. "The fruit of the righteous is a tree of life; and he that is wise winneth souls" (Proverbs 11:30). God's statutes make wise the simple (Psalm 19:8; Psalm 119:98, 99); and they who are thus made wise attract the attention of others by the fame of their wisdom. Thus the Queen of Sheba heard in her distant country of the wisdom of Solomon, and came to him to commune with him of all that was in her heart (1 Kings 10:1, etc.); and many throughout the ages who were seeking after truth among the heathen, were drawn to Israel by seeing how with them was the true knowledge of God. Israel was thus exalted because God was nigh to them, ready to hear their cry and to give them what they needed; which none of the gods of the nations were or could be to their votaries; and because, in the Law which God had given them, they had such instruction and direction as no heathen nation possessed.

4:1-23 The power and love of God to Israel are here made the ground and reason of a number of cautions and serious warnings; and although there is much reference to their national covenant, yet all may be applied to those who live under the gospel. What are laws made for but to be observed and obeyed? Our obedience as individuals cannot merit salvation; but it is the only evidence that we are partakers of the gift of God, which is eternal life through Jesus Christ, Considering how many temptations we are compassed with, and what corrupt desires we have in our bosoms, we have great need to keep our hearts with all diligence. Those cannot walk aright, who walk carelessly. Moses charges particularly to take heed of the sin of idolatry. He shows how weak the temptation would be to those who thought aright; for these pretended gods, the sun, moon, and stars, were only blessings which the Lord their God had imparted to all nations. It is absurd to worship them; shall we serve those that were made to serve us? Take heed lest ye forget the covenant of the Lord your God. We must take heed lest at any time we forget our religion. Care, caution, and watchfulness, are helps against a bad memory.Behold, I have taught you statutes and judgments, even as the Lord my God commanded me,.... He had faithfully delivered them, without adding them, or diminishing from them, and had diligently instructed the Israelites in them, had taken pains to lead them into a thorough knowledge and understanding them:

that ye should do so in the land whither ye go possess it; do in like manner as the commandments the Lord direct to; or that which is right (e); proper and fitting to be done, by doing which they continue in the land they were about to possess, therefore when in it were to be careful to them; some of them could not be done till they came into it, and all were to be done in it.

(e) "rectum".
