16. His heart is cast as hard as stone;cast as the lower millstone.
17. When he rises up, the gods are afraid;when he crashes down, they fall back.
18. Should a sword reach him, it will not avail;nor will spear, dart, or javelin.
19. He regards iron as chaff,and bronze as rotten wood.
20. No arrow will put him to flight;slingstones used against him are but straw.
