7-9. what nation is there so great--Here he represents their privileges and their duty in such significant and comprehensive terms, as were peculiarly calculated to arrest their attention and engage their interest. The former, their national advantages, are described (De 4:7, 8), and they were twofold: 1. God's readiness to hear and aid them at all times; and 2. the excellence of that religion in which they were instructed, set forth in the "statutes and judgments so righteous" which the law of Moses contained. Their duty corresponding to these pre-eminent advantages as a people, was also twofold: 1. their own faithful obedience to that law; and 2. their obligation to imbue the minds of the young and rising generation with similar sentiments of reverence and respect for it.
