נוֹתֵ֣ן לִבְהֵמָ֣ה לַחְמָ֑הּ לִבְנֵ֥י עֹ֝רֵ֗ב אֲשֶׁ֣ר יִקְרָֽאוּ׃
들짐승과 우는 까마귀 새끼에게 먹을 것을 주시는도다
Rashi on Psalms
to the young ravens Our Sages explained that he [the raven] is cruel to his offspring, and the Holy One, blessed be He, has pity on them and prepares for them gnats from their excrement, which enter their mouths.
