(6) This is your wisdom and your understanding in the sight of the nations.--The laws of Jehovah in Israel, and the constant presence of Jehovah with Israel, would make an impression upon the world that it would not be easy to resist. For, he adds, "what nation is there so great, that hath God so nigh unto them?"

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.Keep therefore and do them,..... Observe them, take notice of what is expressed by them, and perform them, both as to matter and manner, as they require:

for this is your wisdom and your understanding in the sight of the nations; that is, their wisdom and understanding would appear to other nations by their observance of the commands of God:

which hear all these statutes; which they had a report, got knowledge of by some of the philosophers who travelled into those parts, and by the translation of the Bible into the Greek language:

and say, surely this great nation is a wise and understanding people; that had such a body of laws, in which they were instructed, and according to which they were governed, and in which they walked; that were so agreeable to reason, truth, justice, and equity; insomuch that so far as they became known they were admired and copied after, both by Greeks and Romans; and hence it was that the oracle (f) declared, that only the Chaldeans and Hebrews were a wise people; the Hebrews came from Chaldea, as Abraham the father of them.
