Job 32:6-9

And Elihu the son of Barachel the Buzite answered and said, I am young, and ye are very old; Wherefore I was afraid, and durst not shew you mine opinion. I said, Days should speak, And multitude of years should teach wisdom. But there is a spirit in man: And the inspiration of the Almighty giveth them understanding. Great men are not always wise: Neither do the aged understand judgment.
