Deuteronomy 8:17 in the King James Version
And thou say in thine heart, My power and the might of mine hand hath gotten me this wealth.
Context
16 who fed you in the wilderness with manna, which your fathers didn’t know, that he might humble you, and that he might prove you, to do you good at your latter end;
17 and lest you say in your heart, “My power and the might of my hand has gotten me this wealth.”
18 But you shall remember the LORD your God, for it is he who gives you power to get wealth, that he may establish his covenant which he swore to your fathers, as it is today.
