'Opinion' in the Bible

And when the Philistine, taking note, saw David, he had a poor opinion of him: for he was only a boy, red-haired and good-looking.

So Achish summoned David and said to him, "As surely as the Lord lives, you are an honest man, and I am glad to have you serving with me in the army. I have found no fault with you from the day that you first came to me until the present time. But in the opinion of the leaders, you are not reliable.
