Job 41:3-5

People keep many animals as pets. But nobody can train a crocodile to be a tame animal. It is out of control.

Men cannot hunt for a crocodile

v6 Merchants will not bargain for the meat of the crocodile. Shopkeepers cannot cut up the meat in order to sell it.

v7 You cannot hunt a crocodile with spears and harpoons, like a large fish. (Spears and harpoons are long knives, like swords.)

v8 If you touch a crocodile, you will have a terrible struggle. And you will never touch a crocodile again.

v9 Do not even imagine that you could control a crocodile. You could never win a fight against a crocodile. When you see the crocodile, you will know this. v10 Nobody dares to upset a crocodile. (But I, God, made the crocodile.) So, be sure that nobody could oppose me. v11 I owe nothing to anyone. Everything belongs to me.
