Deuteronomy 30:8-10

8And you will again obey the voice of the LORD and follow all His commandments I am giving you today. 9So the LORD your God will make you abound in all the work of your hands and in the fruit of your womb, the offspring of your livestock, and the produce of your land. Indeed, the LORD will again delight in your prosperity, as He delighted in that of your fathers, 10if you obey the LORD your God by keeping His commandments and statutes that are written in this Book of the Law, and if you turn to Him with all your heart and with all your soul.
