Deuteronomy 8:13-17

8:13 when your cattle and flocks increase, when you have plenty of silver and gold, and when you have abundance of everything, 8:14 be sure you do not feel self-important and forget the Lord your God who brought you from the land of Egypt, the place of slavery, 8:15 and who brought you through the great, fearful desert of venomous serpents and scorpions, an arid place with no water. He made water flow from a flint rock and 8:16 fed you in the desert with manna (which your ancestors had never before known) so that he might by humbling you test you and eventually bring good to you. 8:17 Be careful not to say, “My own ability and skill have gotten me this wealth.”
