Kabbalah su Isaia 27:1

In the name of Rabbi Shalom, Rabbi Yehuda said that if that is true, what about the Leviathan and the bull, as it is written, "Surely the mountains bring him forth food" (Iyov 40:20). Rabbi Yosi said that it is also written, "On that day, Hashem with His sore and great and strong sword will punish Leviathan the flying serpent, and the Leviathan that crooked serpent; and He will slay the crocodile that is in the sea" (Isaiah 27:1). This was said thrice, to hint at the kingdom. Rabbi Tanchum added that there is nothing to reveal in addition to what the wise men said. This is assuredly so.
