Perek Shira: The Frog - The Symbol of Kiddush Hashem
Rav Yechiel Michel Stern in the Nishmas Kol Chai points out that we find time and time again the frogs taking up their mission for Hashem fearlessly without any concern for their own death. By the Maka of tzefardei'a we find frogs jumping into burning ovens. Then we find in the medrash, when Hashem wanted to kill a person in Eiver HaYarden with a scorpion who couldn't swin across the Yarden, the frog carried the dangerous scorpion across without worrying that the scorpion will bite him. In the Hakdama of Perek Shira we find the frog offering himself as food for a species that lives on the edge of the river that eats frogs. The frog doesn't run. He makes himself readily available to fulfill the Tzivui Hashem.
To have a moment of clarity and be Moseir Nefesh is a great thing. Once you have earned your wings and still come out alive, you may be more reluctant to take your chances again the next time. Not so with the frogs. Their whole essence is Kiddush Hashem, over and over again. They sing day and night and don't ever stop croaking. What are they croaking? The song of complete Mesiras Nefesh to the great King, "Boruch Shem Kevod Malchuso L'Olam Va'ed." Hashem's Kingdon is blessed for all eternity.
