What does Job Chapter 6 say, and which statements belong to its speaker?

Answering his companion Eliphaz, Job declared that if his provoked grief and the calamity he suffered were weighed together upon a balance, his affliction would prove heavier than all the sand of the seashore, explaining why his words were filled with overwhelming sorrow. He cried that the piercing arrows of the Lord were sunk within him, their rage drinking up his spirit while divine terrors marshaled against him. Just as the wild donkey does not bray when pasture is abundant and the ox does not low beside a full manger, Job asked whether unsavory food could be eaten without salt, and whether a thing can be tasted which brings death when tasted; food that was formerly rejected as distasteful and unsavory had now become his sorrowful sustenance. A Challoner annotation notes that Job did not compare his sufferings to genuine guilt, but rather contrasted his actual calamity with the imaginary crimes his companions presumed against him and the impatience they charged to his account.

Yearning for an end to his agony, Job pleaded that God would grant his one desire: that the Almighty who had begun to strike him would let loose His hand and cut off his life completely. He said it would be his comfort that, amid sorrow, God would not spare him, and that he would not contradict the words of the Holy One. Job asked what strength he had to hold out and what end he had to act patiently, protesting that his body was not carved of stone nor was his flesh forged of brass. Finding no inner resource to sustain himself, he lamented that his familiar friends had abandoned him in his misery.

Turning upon his visitors, Job declared that anyone who withholds mercy from an afflicted friend forsakes the fear of the Almighty. He likened his brethren to deceitful torrents in the valleys that swell with ice and melting snow, but vanish into nothingness when heat comes. He spoke of the paths of Thema and ways of Saba, of waiting and confidence followed by shame; in the same manner, his companions beheld his affliction and shrank back in fear. Challenging their harsh censures, Job pointed out that he had never begged for their wealth, asked for their substance, or asked them to rescue him from powerful foes. He demanded that they show him his actual errors if he had spoken wrongly, reproaching them for preparing words to rebuke speeches like wind, rushing upon the fatherless and endeavoring to overthrow their friend. Urging them to cease contentious debate and examine his speech with equity, Job affirmed that his lips harbored no iniquity or folly.
