Deuteronomy 30:6-10 New Revised Standard Version (NRSV)
6 Moreover, the Lord your God will circumcise your heart and the heart of your descendants, so that you will love the Lord your God with all your heart and with all your soul, in order that you may live. 7 The Lord your God will put all these curses on your enemies and on the adversaries who took advantage of you. 8 Then you shall again obey the Lord, observing all his commandments that I am commanding you today, 9 and the Lord your God will make you abundantly prosperous in all your undertakings, in the fruit of your body, in the fruit of your livestock, and in the fruit of your soil. For the Lord will again take delight in prospering you, just as he delighted in prospering your ancestors, 10 when you obey the Lord your God by observing his commandments and decrees that are written in this book of the law, because you turn to the Lord your God with all your heart and with all your soul.
