Deuteronomy 8:1-2

Amplified Bible, Classic Edition

8 All the commandments which I command you this day you shall be watchful to do, that you may live and multiply and go in and possess the land which the Lord swore to give to your fathers.

² And you shall [earnestly] remember all the way which the Lord your God led you these forty years in the wilderness, to humble you and to prove you, to know what was in your [mind and] heart, whether you would keep His commandments or not.
