Deuteronomy 30:9-10

Then the LORD your God will prosper you abundantly in all the work of your hand, in the offspring of your body and in the offspring of your cattle and in the produce of your ground, for the LORD will again rejoice over you for good, just as He rejoiced over your fathers; if you obey the LORD your God to keep His commandments and His statutes which are written in this book of the law, if you turn to the LORD your God with all your heart and soul.
