Deuteronomy 8:15-17

American Standard Version

¹⁵ who led thee through the great and terrible wilderness, wherein were fiery serpents and scorpions, and thirsty ground where was no water; who brought thee forth water out of the rock of flint; ¹⁶ who fed thee in the wilderness with manna, which thy fathers knew not; that he might humble thee, and that he might prove thee, to do thee good at thy latter end: ¹⁷ and lest thou say in thy heart, My power and the might of my hand hath gotten me this wealth.
