Lamentations 4:13
For the sins of her prophets, and the iniquities of her priests, that have shed the blood of the just in the midst of her, For the sins of her prophets, and the iniquities of her priests, that have shed the blood of the just in the midst of her,
The sins of Jerusalem's prophets and the iniquities of its priests caused the blood of just people to be shed in the midst of the city. That shedding of innocent blood belonged to those very sins and iniquities of the prophets and priests. Those sins brought calamity upon the city.
