Deuteronomy 8:16-18

Young's Literal Translation

¹⁶ who is causing thee to eat manna in the wilderness, which thy fathers have not known, in order to humble thee, and in order to try thee, to do thee good in thy latter end),

¹⁷ and thou hast said in thy heart, My power, and the might of my hand, hath made for me this wealth:

¹⁸ `And thou hast remembered Jehovah thy God, for He it [is] who is giving to thee power to make wealth, in order to establish His covenant which He hath sworn to thy fathers as [at] this day.
