For the LORD gives wisdom, and from his mouth come knowledge and understanding.

Get wisdom! Get understanding! Do not forget or turn aside from the words of my mouth!

For my mouth speaks the truth wickedness is detestable to me.

As vinegar is to the mouth and smoke to the eyes, so is the lazy person to those who send him.

A discerning mind seeks knowledge, but the mouth of fools feeds on stupidity.

Even a fool is thought to be wise when he remains silent; he is thought to be prudent when he keeps his mouth shut.

A fool's words bring strife, and his mouth invites fighting.

A fool's mouth is his unraveling, and his lips entrap himself.

The lazy person buries his hand in his dish and doesn't bother to bring it back to his mouth.

Bread gained by deceit is sweet to a man, but later his mouth will be full of gravel.

Whoever watches his mouth and tongue keeps himself from trouble.

The mouth of an immoral woman is a deep pit; a man experiencing the LORD's wrath will fall into it.

The lazy person buries his hand in the dish, but he's too tired to bring it to his mouth again.

A lying tongue hates its victims, and a flattering mouth causes ruin.

Let someone else praise you, not your own mouth; a stranger, and never your own lips.

This is what an immoral woman is like: she eats, wipes her mouth, then says "I've done nothing wrong."

If you've foolishly exalted yourself or if you've plotted evil, put your hand over your mouth.
