Deuteronomy 30:1-3

“In the future, when you experience all these blessings and curses I have listed for you, and when you are living among the nations to which the LORD your God has exiled you, take to heart all these instructions. If at that time you and your children return to the LORD your God, and if you obey with all your heart and all your soul all the commands I have given you today, then the LORD your God will restore your fortunes. He will have mercy on you and gather you back from all the nations where he has scattered you.
