Deuteronomy 8:14, 17-18

be careful that your heart doesn’t become proud and you forget the LORD your God who brought you out of the land of Egypt, out of the place of slavery.

You may say to yourself, ‘My power and my own ability have gained this wealth for me,’ but remember that the LORD your God gives you the power to gain wealth, in order to confirm his covenant he swore to your ancestors, as it is today.
