Remember the long way that the Lord your God has led you these forty years in the wilderness, in order to humble you, testing you to know what was in your heart, whether or not you would keep his commandments.

and when your herds and flocks have multiplied, and your silver and gold is multiplied, and all that you have is multiplied,
