'Fishing' in the Bible

The Chaldeans pull them all up with a hook,catch them in their dragnet,and gather them in their fishing net;that is why they are glad and rejoice.

That is why they sacrifice to their dragnetand burn incense to their fishing net,for by these things their portion is richand their food plentiful.

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