Job 32:3-7

Also against his three friends was his wrath kindled, because they had found no answer, and yet had condemned Job.

Now Elihu had waited till Job had spoken, because they were elder than he.

When Elihu saw that there was no answer in the mouth of these three men, then his wrath was kindled.

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.
