Dove with Olive Branch

In Parshat Noach, Noah sent a dove twice to check if the flood was over. The dove returned with an olive branch, a sign of peace and healing. Kabbalah says a bird symbolizes Hashem's name: the head is yud, the body is vav, and the wings are hehs. The Tanya and Shaar Hayechudim say the wings are awe and love of G-d, which uplift the mitzvot. The Talmud says the dove is like the Jewish people, who are exalted even in exile and fight with their wings (mitzvot) not their beaks.
