Job 32:15-16

They were amazed Job's three friends stood mute, like persons amazed, not knowing what to reply to his arguments, and wondering at his bold and confident assertions concerning his integrity, and his interest in the favour of God, under such terrible and manifest tokens, as they thought them, of God's just displeasure against him. They answered no more Although Job gave them just occasion to confute and reprove him for his intemperate speeches, and his presumptuous and irreverent expressions concerning God. When I had waited they spake not, &c. Which he repeats as a strange and unreasonable thing, that they should be silent when they had such obligations to speak for the vindication both of God's justice, and of their own truth and reputation.
