Deuteronomy 30:8-10

8And thou shalt return and obey the voice of the LORD, and do all his commandments which I command thee this day. 9And the LORD thy God will make thee to abound in every work of thy hand, in the fruit of thy body, and in the fruit of thy cattle, and in the fruit of thy land, for good: for the LORD will again rejoice over thee for good, as he rejoiced over thy fathers: 10If thou shalt hearken to the voice of the LORD thy God, to keep his commandments and his statutes which are written in this book of the law, and if thou shalt turn to the LORD thy God with all thy heart, and with all thy soul.
