Job 12:12
12 Wisdom is with kthe aged,
and understanding in length of days.
Job 32:6–7
6 And Elihu the son of Barachel the Buzite answered and said:
“I am young in years,
and you are zaged;
therefore I was timid and afraid
to declare my opinion to you.
7 I said, ‘Let days speak,
and many years teach wisdom.’
