Deuteronomy 30:8-10

8 And you shall return and obey the voice of the LORD, and do all his commandments which I command you this day.

9 And the LORD your God will make you plenteous in every work of your hand, in the fruit of your body, and in the fruit of your cattle, and in the fruit of your land, for good: for the LORD will again rejoice over you for good, as he rejoiced over your fathers:

10 If you shall listen to the voice of the LORD your God, to keep his commandments and his statutes which are written in this book of the law, and if you turn to the LORD your God with all your heart, and with all your soul.
