"Therefore he sacrifices to his net and burns incense to his dragnet, for by his net he lives in luxury and enjoys the choicest food." NIV translation
The Babylonians thought that they were so superior to everyone else because of their conquest of so many other nations. That military power brought them wealth and they really lived it up. The same thing is happening in our world today as there is a rush to have the best and biggest military and, in many cases, that military power has become a false god. Many have turned away from trusting in the power of God and turned to trusting in a military machine.
"Is he to keep on emptying his net, destroying nations without mercy?" NIV translation
Habakkuk ends this chapter with a simple question to God which is:
Are you going to allow the evil Babylonians to continue to win victories?
