'Conceit' in the Bible

The rich man's wealth is his strong city, and as an high wall in his own conceit.

Answer a fool according to his folly, lest he be wise in his own conceit.

Seest thou a man wise in his own conceit? there is more hope of a fool than of him.

The sluggard is wiser in his own conceit than seven men that can render a reason.

The rich man is wise in his own conceit; but the poor that hath understanding searcheth him out.
