Deuteronomy 8:1-2

Do Not Forget the LORD 1Be careful to follow every command I am giving you today, so that you may live and increase and may enter and possess the land the LORD promised on oath to your ancestors. 2Remember how the LORD your God led you all the way in the wilderness these forty years, to humble and test you in order to know what was in your heart, whether or not you would keep his commands.
