Deuteronomy 4:5-6

Brenton(i) 5 Behold, I have shewn you ordinances and judgments as the Lord commanded me, that ye should do so in the land into which ye go to inherit it. 6 And ye shall keep and do them: for this is your wisdom and understanding before all nations, as many as shall hear all these ordinances; and they shall say, Behold, this great nation is a wise and understanding people.
