Deuteronomy 8:19

¹⁷ You might say in your heart, “The power and strength of my hands have made this wealth for me.”

¹⁸ But remember that it is the LORD your God who gives you the power to gain wealth, in order to confirm His covenant that He swore to your fathers even to this day.

If you ever forget the LORD your God and go after other gods to worship and bow down to them, I testify against you today that you will surely perish.

²⁰ Like the nations that the LORD has destroyed before you, so you will perish if you do not obey the LORD your God.

Do read the surrounding verses too, because the context often says more than a single verse.
