Adam Clarke on Habakkuk 1:14

Makest men as the fishes of the sea - Easily are we taken and destroyed. We have no leader to guide us, and no power to defend ourselves. Nebuchadnezzar is here represented as a fisherman, who is constantly casting his nets into the sea, and enclosing multitudes of fishes; and, being always successful, he sacrifices to his own net - attributes all his conquests to his own power and prudence; not considering that he is only like a net that after having been used for a while, shall at last be thrown by as useless, or burnt in the fire.
