'Conceit' in the Bible

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.
