God enforces his law with the warning of wrath and judgment on those who shed innocent blood.
“This is what the Sovereign LORD says: A city that brings on herself doom by shedding blood in her midst…you have become guilty because of the blood you have shed” (Ez 22:3).
The Lord sent… Chaldeans …against Judah to destroy it…Surely this came upon Judah at the command of the Lord, to remove them out of his sight, for the sins of Manasseh, according to all that he had done, and also for the innocent blood that he had shed. For he filled Jerusalem with innocent blood and the Lord would not pardon” (2 Ki 24:2-4).
