'Fishing' in the Bible

The adversary captures them with a hook, gathering them up in a fishing net. He collects them with a dragnet, rejoicing and gloating over his catch.

Therefore he sacrifices to his fishing net, and burns incense in the presence of his dragnet, because by them his assets increase and he gets plenty of food.

Is he to continue to empty his fishing net? Will he ever stop killing entire nations without mercy?"
