Deuteronomy 30:8-10

American Standard Version

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