And what the gods did, the same is done now. Evil, indeed, does not now beset this (Sacrificer), but when he now does this, it is that he wants to do what the gods did; and he thereby drives off whatever evil, whatever foe besets him; and because, by means of them, he drives off the foe, evil, therefore they are (called) the 'foeless' (bricks). He places them on every side: he thereby drives off the foe, evil, on every side. He places them on the other side: from his whole self he thereby drives off the foe, evil.
