Deuteronomy 4:6
5, 6. this is your wisdom and your understanding in the sight of the nations, which shall hear all these statutes—Moses predicted that the faithful observance of the laws given them would raise their national character for intelligence and wisdom. In point of fact it did do so; for although the heathen world generally ridiculed the Hebrews for what they considered a foolish and absurd exclusiveness, some of the most eminent philosophers expressed the highest admiration of the fundamental principle in the Jewish religion—the unity of God; and their legislators borrowed some laws from the constitution of the Hebrews.
Deuteronomy 27:9
5-10. there shalt thou build an altar . . . of whole stones—The stones were to be in their natural state, as if a chisel would communicate pollution to them. The stony pile was to be so large as to contain all the conditions of the covenant, so elevated as to be visible to the whole congregation of Israel; and the religious ceremonial performed on the occasion was to consist: first, of the elementary worship needed for sinful men; and secondly, of the peace offerings, or lively, social feasts, that were suited to the happy people whose God was the Lord. There were thus, the law which condemned, and the typical expiation—the two great principles of revealed religion.
