Job 41:24-26

The Voice

²⁴     Its heart is rock hard,
        as hard as a lower millstone, impervious to grinding.
²⁵     When the beast rises up and moves near, the mighty ones shudder in fear;
        when it crashes down, they retreat.
²⁶     The sword that reaches it may strike but to no effect,
        so, too, the spear, the dart, and the lance.
