Deuteronomy 8:17 in the World English Bible
and lest you say in your heart, “My power and the might of my hand has gotten me this wealth.”
Context
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 thou say in thine heart, My power and the might of mine hand hath gotten me this wealth.
18 But thou shalt remember the LORD thy God: for it is he that giveth thee power to get wealth, that he may establish his covenant which he sware unto thy fathers, as it is this day.
