Job 32:17,18

I am full of matter I have many things to say in this cause; the spirit within me constraineth me My spirit, or soul, is so entirely dissatisfied with what hath hitherto been spoken, and so clearly apprehends what may silence Job and end the dispute, that it forceth me to speak. Or rather he means, that God's Spirit had so enlightened his understanding by discovering the truth of the matter to him, and had so inspired him with zeal, that he was constrained thereby to plead God's cause against Job. “As he was a young man,” says Heath, “he dared not claim much authority from his own sayings; but he claims it from the inspiration of the Almighty, by whose Spirit he was actuated, and whose oracles he was delivering.”
