All the commandments which I command you this day shall you observe to do, that you may live, and multiply, and go in and possess the land which the LORD swore unto your fathers. And you shall remember all the way which the LORD your God led you these forty years in the wilderness, to humble you, and to test you, to know what was in your heart, whether you would keep his commandments, or not. (Deuteronomy 8:1-2)
