נוֹתֵ֣ן לִבְהֵמָ֣ה לַחְמָ֑הּ לִבְנֵ֥י עֹ֝רֵ֗ב אֲשֶׁ֣ר יִקְרָֽאוּ׃
El da á la bestia su mantenimiento, Y á los hijos de los cuervos que claman.
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.
