Deuteronomy 8:14-15

14Then be careful! Do not become proud. Never forget the Lord your God who brought you out of Egypt. He rescued you from the place where you were slaves.

15He led you through the large and terrible desert where there were dangerous snakes and scorpions. It was very hot and dry. There was no water there for you to drink. But the Lord made water pour out of a hard rock for you.
