Job 32:15 - Matthew Poole's English Annotations on the Holy Bible

They, i.e. Job's three friends, of whom he speaks some times, in the second, and here in the third person, directing his speech to Job and the auditors of this disputation. Were amazed; they stood mute, like persons amazed, not knowing what to reply to Job's arguments, and wondering at his bold and confident assertions of his integrity, and of his interest in God, under such sad and manifest tokens of God's just displeasure against him. They answered no more, although Job gave them just occasion to reprove and confute him for his intemperate speeches and presumptuous and irreverent expressions concerning God.
