The Lord God continues to put Job in his place (read all of Job 40-41).
Job 41:1 Canst thou draw out leviathan with an hook? or his tongue with a cord which thou lettest down?
The Lord continues to question Job and describe Leviathan:
Canst thou put an hook into his nose?
bore his jaw through with a thorn?
Will he make many supplications unto thee?
will he speak soft words unto thee?
Will he make a covenant with thee?
wilt thou take him for a servant forever?
Wilt thou play with him as with a bird?
wilt thou bind him for thy maidens?
Shall the companions make a banquet of him?
shall they part him among the merchants?
Canst thou fill his skin with barbed irons?
his head with fish spears?
It would appear that Leviathan is a massive sea-monster who’s impervious to human weapons, breathes fire, and emits smoke from his nostrils.
Psalm 74:13-14 Thou didst divide the sea by thy strength: thou brakest the heads of the dragons in the waters. Thou brakest the heads of leviathan in pieces, and gavest him to be meat to the people inhabiting the wilderness.
Psalm 104:24-27 O LORD, how manifold are thy works! in wisdom hast thou made them all: the earth is full of thy riches. So is this great and wide sea, wherein are things creeping innumerable, both small and great beasts. There go the ships: there is that leviathan, whom thou hast made to play therein. These wait all upon thee; that thou mayest give them their meat in due season.
Could this be a reference to Satan?
Isaiah 27:1 In that day the LORD with his sore and great and strong sword shall punish leviathan the piercing serpent, even leviathan that crooked serpent; and he shall slay the dragon that is in the sea.
