Deuteronomy 8:15-18

15He was the one who led you through that vast and dangerous desert—a thirsty and arid land, with poisonous snakes and scorpions. He was the one who made water come out of solid rock for you.

16He was the one who fed you in the desert with manna, which your ancestors had never seen. He did this in order to humble you and test you. But he also did this so that things would go well for you in the end.

17You may say to yourselves, “I became wealthy because of my own ability and strength.”

18But remember the Lord your God is the one who makes you wealthy. He’s confirming the promise  which he swore to your ancestors. It’s still in effect today.
