'Blood' in the Bible

Because thou hast plundered many nations, all the rest of the peoples shall plunder thee; because of men's blood, and for the violence done to the land, to the city, and all that dwell therein.

Woe to him that buildeth a town with blood, and establisheth a city by unrighteousness!

For the violence done to Lebanon shall cover thee, and the destruction of beasts which made them afraid; because of men's blood, and for the violence done to the land, to the city, and all that dwell therein.
