Adam Clarke on Job 32:15

They were amazed - Mr. Good translates: "They (the speeches) are dissipated; they no longer produce effect; the words have flirted away from them." Your words, being without proper reference and point, are scattered into thin air: there is nothing but sound in them; they are quite destitute of sense. But I prefer the words as spoken of Job's friends. They took their several parts in the controversy as long as they could hope to maintain their ground: for a considerable time they had been able to bring nothing new; at last, weary of their own repetitions, they gave up the contest.
