Deuteronomy 4:6

Keep therefore and do them So eight times in D (as also eight in P); the similar keep(or observe) to dooccurs some 20 times both with Sg. and Pl. This practical emphasis is characteristic of the Book. Men are often content to remember the commandments.

for this is your wisdom and your understanding Not your mere possession of the law, but this your doing of it, shall be your intellectual strength. Cp. John 7:17.

in the sight of the peoples, which shall … say So actually it came to pass. Loyalty to the Law ensured not only the national existence of Israel (see on Deuteronomy 4:1), but their fame among the Gentiles; who shall say, This great nation is a wise and understanding people. Most signally fulfilled by the fame of the Jews among illuminated Greeks after Alexander's conquest of Asia. Hecataeus of Abdera, Clearchus, Theophrastus, Megasthenes, Hermippus all call the Jews the philosophersof the East (Jerusalem, ii. 401, etc.). The cause of such a fame was not of course the wise details of the Law, nor even that the nation possessed and lived by it, in a way unparalleled by any nation in W. Asia the Greeks find the nearest parallel in India but the religious spirit of the Law, its unique monotheism. And so the discourse now proceeds to speak of Israel's God.

Surely Heb. raḳ. See on Deuteronomy 10:15.
