Deuteronomy 30:9-10

Then the LORD your God shall make you abundantly prosperous in everything that you do, in the offspring of your body and in the offspring of your cattle and in the produce of your land; for the LORD will again delight over you for good, just as He delighted over your fathers, if you listen to and obey the voice of the LORD your God to keep His commandments and His statutes which are written in this Book of the Law, and if you turn to the LORD your God with all your heart and with all your soul (your entire being).
