The LORD your God will circumcise your heart and the hearts of your descendants, and you will love Him with all your heart and all your soul so that you will live. The LORD your God will put all these curses on your enemies who hate and persecute you. Then you will again obey Him and follow all His commands I am giving you today. HSCB
