Woe to him who builds a city with bloodshed
and establishes a town by crime!
Has not the LORD Almighty determined
that the people's labour is only fuel for the fire,
that the nations exhaust themselves for nothing?
For the earth will be filled with the knowledge of the glory of the LORD,
as the waters cover the sea.
--Habakkuk 2:12-14 (NIV)
A necessary reminder.
