In Yom Hahu HASHEM
with His cherev hakashah v'hagedolah v'hachazakah (terrible and great and strong sword)
shall punish Leviathan the Nachash bari'ach (fleeing serpent),
even Leviathan that Nachash akallaton (crooked serpent);
and He shall slay the Tanin (serpent, devouring sea monster) that is in the sea.
