Deuteronomy 4:29-31

New Revised Standard Version, Anglicised

²⁹ From there you will seek the Lord your God, and you will find him if you search after him with all your heart and soul. ³⁰ In your distress, when all these things have happened to you in time to come, you will return to the Lord your God and heed him. ³¹ Because the Lord your God is a merciful God, he will neither abandon you nor destroy you; he will not forget the covenant with your ancestors that he swore to them.
