Another matter is that the sea is vast, and it speaks of the fourth kingdom that rules the world. There are countless creeping things there. There are countless decrees written against us. There are small creatures with large ones, like dukes, princes, and governors. There are ships that sail there, and these are the ships that they make for Israel, which they write about every day. This Leviathan was formed by You, and anyone who accompanies it will become a laughingstock with it in the World to Come."
Levi and the Messiah of Leviathan
Midrash Tehillim 104:14
