Deuteronomy 8:15-20

15 Do 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!
16 He 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.
17 He did all this so you would never say to yourself, ‘I have achieved this wealth with my own strength and energy.’
18 Remember the LORD your God. He is the one who gives you power to be successful, in order to fulfill the covenant he confirmed to your ancestors with an oath.
19 “But I assure you of this: If you ever forget the LORD your God and follow other gods, worshiping and bowing down to them, you will certainly be destroyed.
20 Just as the LORD has destroyed other nations in your path, you also will be destroyed if you refuse to obey the LORD your God.
