Let’s start with a nice friendly neighborhood warning:
“Woe to him who gets evil gain for his house, to set his nest on high, to be safe from the reach of harm! (Habakkuk 2:9 ESV)
Habakkuk is talking about the Chaldeans who have established security in their lives and their families lives building ‘houses’ that they think will keep them safe from the reach of harm.
God calls this evil for two reasons.
First, because of how they gained their safety. They have established their security by ‘cutting off many peoples’, by shaming others, by the blood of man.
