Divrey Hayamim Bais 30:9

For if ye turn again unto Hashem, your achim and your banim shall find rachamim before them that lead them captive, so that they shall come back into HaAretz HaZot, for Hashem Eloheichem is channun (gracious) and rachum (compassionate), and will not turn away His face from you, if ye return unto Him.
