Adam Clarke on Lamentations 4:13

For the sins of her prophets, and the iniquities of her priests - These most wretched beings, under the pretense of zeal for the true religion, persecuted the genuine prophets, priests, and people of God, and caused their blood to be shed in the midst of the city, in the most open and public manner; exactly as the murderous priests, and blood-thirsty preachers, under the reign of bloody Queen Mary, did in England. However, the profligate priests and idolatrous prophets in Jerusalem, only shed the blood of the saints of God there: but the sanguinary papists, in the above reign, burnt the blood here, for they burnt the people alive; and at the same time, in their worse than Molochean cruelty, consigned, with all the fervor peculiar to their then ruthless Church, the souls of those whom they thus massacred, to the bitter pains of eternal death! O earth, cover not thou their blood!
