Комментарий о цитате к Тегилим 105:30

"Let the waters swarm:" Shorets (swarm) is always an intransitive verb - and its main connotation is about the movement and running of animals that are not high off the ground, whether they don't have legs or whether they have legs. And [the following creatures] are called sherets (according to the words of Rashi): "Every living thing that is not very high... among flying creatures, such as flies; among the insects, such as ants... and worms; and among the [four legged] creatures, such as the weasel, the mouse, the lizard, and their like; and all of the fish." And the explanation of "and let the waters swarm" is not that the waters should bring out and propagate them, but [rather] that the waters appear moving with them. And so [too is the understanding of] "And the Nile will swarm frogs" (Exodus 7:28), [and] "Their land swarmed frogs" (Psalms 105:30) - the Nile and the land appeared to be moving because of the movement of the frogs - brulicare in [Italian] (wimmeln in Yiddish). And so [too is the understanding of] "And all the living souls that will swarm" (Ezekiel 47:9) - the river [in the continuation of the verse] is called swarming because of the swarming of the living souls within it. And this [usage] is like [that] in "withering its leaves" (Isaiah 1:30) - the tree is called withering because of the withering of its leaves; and also "only the throne shall I be greater than you" (Genesis 41:40) [means] I will be greater than you in view of the throne, with the throne.
