The Torah (Bible) talks about the importance of chasing a mother bird from its nest before taking its fledglings. Commentators believe this reflects the state of the Jewish People in exile. The mothers bird who has been chased away cries about the separation from her children. When Hashem (God) hears these cries, he compares the suffering of the mother bird to His own fate. Hashem’s  presence has been driven out of the Beit Hamikdash (Holy Temple), and His children have been driven into exile. The Jewish People must return to their homeland and restore the Beit Hamikdash so that Hashem’s presence can once again dwell in Yerushalayim (Jerusalem).
