John Trapp on Job 32:7

Verſe 7. I ſaid, Dayes ſhould ſpeak] This ſeems to have been a Proverb in thoſe dayes; and it ran much in Elihu's mind. We uſe to ſay, That at meetings young men ſhould be Mutes, and old men Vowels: Of Arſatius, who ſucceeded Chryſoſtom in the Sea of Conſtantinople, Antonin. tit. 10. c. 9. it is recorded (but nothing to his commendation) that at eighty years of age, he was as eloquent as a Fiſh, and as nimble as a Frog.

And multitude of years ſhould teach wiſdom] Heb. Should make known wiſdom: ſc. ſuch as conſiſteth in the knowledge of God and of his will, of our ſelves and of our duties. This is far beyond all that of the Heathen Sages, of the Seven wiſe Men of Greece, [non-Latin text not transcribed] Plut. of Archimedes of Syracuſe, who had a name and ſame, ſaith Plutarch, not of humane, but of a kind of divine wiſdom: So had Socrates, ſo had Apollonius, of whom Philoſtratus ſaith, that he was non doctus, ſed natus ſapicus, not taught, but born a wiſe man. Theſe all were the worlds wizards; and what they came to, ſee Rom. Inſtit. l. 3. c. 30. 1. & 1 Cor. 1. & 2. Lactantius truly telleth us, in the name of the whole community of Chriſtians, That all the wiſdom of a man conſiſteth in this, to know God and worſhip him aright. And that theſe Seniours ſhould have taught and notified ſuch wiſdom, Elihu had well hoped: but it proved otherwiſe.
