Habacuc 2:12

12. Town… city Synonymous; they cannot be restricted to the capital, but include cities scattered throughout the empire, wherever building enterprises were carried on.

Blood,… iniquity Blood was shed and iniquity done in subduing the nations, in tearing them from their homes and transporting them to Babylonia, and in compelling them to assist in the extensive building enterprises of which the inscriptions of Nebuchadnezzar give a fair idea. The sentiment expressed here is of universal application, but the prophet has in mind primarily the Chaldeans (compare Micah 3:10; Jeremiah 22:13).
