Some interpreters suggest that Leviathan is a symbol of mankind in opposition to God, claiming that it and beasts mentioned in the books of Daniel and Revelation should be interpreted as metaphors. The usage of Leviathan in the Old Testament books (Isaiah 27:1) would seem to be a reference to a Semitic mythological beast mentioned in Ugaritic literature (of Ugarit, a city-state in North Syria). According to Canaanite myth, the Leviathan was an enemy of order in Creation and was slain by the Canaanite god Baal. The word Leviathan to the ancient Jews became synonymous with that which warred against God's kingdom. This especially included nations warring against Israel such as Assyria and Egypt.
