וְשָׁרַץ הַיְאֹר צְפַרְדְּעִים וְעָלוּ וּבָאוּ בְּבֵיתֶךָ וגו' וּבְתַנּוּרֶיךָ וּבְמִשְׁאֲרוֹתֶיךָ (ז, כח)
And the river will swarm with frogs, and they will go up and come into your house... and into your ovens and into your kneading bowls. (7:28)
The Frogs Spoke to The Stones:
The Medrash (Shemos Rabbah 10:3) states that during the plague of tzefardea, if a wall was made of marble stones and the frogs could not get through, the frogs would tell the marble to split so that it could go and do Hashem’s will. The Bais Avrohom of Slonim zy”a (Yalkut Sichos Kodesh) quotes his father, the Divrei Shmuel zy”a, as saying: “a Yid must tell his heart to split open in order to allow him to do the will of Hashem. If one doesn’t do this, he is worse than the frogs who told this to the marble so that they could fulfill Hashem’s will.”
