Deuteronomy 8:12-17

12For when you have become full and prosperous and have built fine homes to live in,

13and when your flocks and herds have become very large and your silver and gold have multiplied along with everything else, be careful!

14Do not become proud at that time and forget the Lord your God, who rescued you from slavery in the land of Egypt.

15Do not forget that he led you through the great and terrifying wilderness with its poisonous snakes and scorpions, where it was so hot and dry. He gave you water from the rock!

16He fed you with manna in the wilderness, a food unknown to your ancestors. He did this to humble you and test you for your own good.

17He did all this so you would never say to yourself, ‘I have achieved this wealth with my own strength and energy.’
