that day

"And that day will two monsters be parted, one monster, a female named Leviathan in order to dwell in the abyss of the ocean over the fountains of water; and (the other), a male called Behemoth, which holds his chest in an invisible desert whose name is Dundayin, east of the garden of Eden." - 1 Enoch 60:7-8

There is another Jewish hymn recited on the festival of Shavuot (celebrating the giving of the Torah), known as Akdamut, wherein it says: "...The sport with the Leviathan and the ox (Behemoth)...When they will interlock with one another and engage in combat, with his horns the Behemoth will gore with strength, the fish [Leviathan] will leap to meet him with his fins, with power. Their Creator will approach them with his mighty sword [and slay them both]." Thus, "from the beautiful skin of the Leviathan, God will construct canopies to shelter the righteous, who will eat the meat of the Behemoth [ox] and the Leviathan amid great joy and merriment, at a huge banquet that will be given for them." Some rabbinical commentators say these accounts are allegorical (Artscroll siddur, p. 719), or symbolic of the end of conflict.
