Adam Clarke on Job 13:12

Your remembrances are like unto ashes - Your memorable sayings are proverbs of dust. This is properly the meaning of the original: זכרניכם משלי אפר zichroneycem mishley epher. This he speaks in reference to the ancient and reputedly wise sayings which they had so copiously quoted against him.

Your bodies to bodies of clay - This clause is variously translated: Your swelling heaps are swelling heaps of mire. That is, Your high-flown speeches are dark, involved, and incoherent; they are all sound, no sense; great swelling words, either of difficult or no meaning, or of no point as applicable to my case.
