Terrible as Behemoth is, he is not our greatest enemy; that title belongs to Leviathan, the sea monster.
Who or what is Leviathan? Like Behemoth, he is no ordinary animal. He is an amazing and beautiful creature, who evokes awe and wonder (verses 12-24). He is immensely powerful, and apparently indestructible; nobody can withstand his attacks, and no human weapon can touch him (verses 25-29). He terrorises the earth – yet is himself without fear – and is the ruler of all those who oppose God (verse 34).
There is really only one candidate: Satan, the Accuser, who plays such a large role in the first two chapters of the book of Job and then inexplicably disappears from the story. And this is confirmed by most other references to Leviathan in the Bible; he is a force of evil, opposed to God (Psalm 74:12-14) and doomed to destruction on the Day of Judgement (Isaiah 27:1).
We should not make the mistake of underestimating Leviathan (verses 1-9); he is highly dangerous. We cannot broker a deal with him (verse 4); we dare not try to make a pet of him (verse 5); we cannot use him to further our own ends. He is stronger than we are, and we must never forget it! Only the armour of God (Ephesians 6:13) can give us protection against him.
For there is One who is stronger and more terrible than Leviathan, the One who is supreme over all things. God can – and will – defeat him; He is greater than all the dangers that threaten us and all the problems that beset us. Absolutely everything in this world – no matter how dark or how painful – is held within the Creator’s hands. And we cannot be defeated by them, if we belong to Him. “In all these things we are more than conquerors through Him who loved us.” (Romans 8:37)
