A prudent man concealeth knowledge; But the heart of fools proclaimeth foolishness.
The tongue of the wise uttereth knowledge aright; But the mouth of fools poureth out folly.
A fool hath no delight in understanding, But only that his heart may reveal itself.
Yea also, when the fool walketh by the way, his understanding faileth him, and he saith to every one (that) he is a fool.
