'Opinion' in the Bible

Elihu the son of Barachel the Buzite answered, "I am young, and you are very old; Therefore I held back, and didn't dare show you my opinion.

Therefore I said, 'Listen to me; I also will show my opinion.'

I also will answer my part, and I also will show my opinion.

A fool has no delight in understanding, but only in revealing his own opinion.
