Gregory of Nazianzus

I know the glittering sword, and the blade made drunk in heaven, bidden to slay, to bring to nothing, to make childless and to spare neither flesh nor marrow nor bones. I know him who, though free from passion, meets us like a bear robbed of her cubs, like a leopard in the way of the Assyrians, not only those of that day, but if anyone now is an Assyrian in wickedness. Nor is it possible to escape the might and speed of his wrath when he watches over our impieties, and his jealousy, which knows to devour his adversaries, pursues his enemies to the death. I know the emptying, the making void, the making waste, the melting of the heart and knocking of the knees together;7 such are the punishments of the ungodly.
