Deuteronomy 30:8-10

8Then you will again obey him and follow all his commands I am commanding you today.

9The Lord your God will make you prosper abundantly in all the work of your hands, your offspring, 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 ancestors,

10when you obey the Lord your God by keeping his commands and statutes that are written in this book of the law and return to him with all your heart and all your soul.
