Deuteronomy 8:14-15

14then your heart will become 1proud and you will 2forget the Lord your God who brought you out from the land of Egypt, out of the house of 3slavery.

15He led you through 4the great and terrible wilderness, with its 5fiery serpents and scorpions and thirsty ground where there was no water; He 6brought water for you out of the rock of flint.
