General references

Wisdom rests in the heart of one who has understanding,
But in the hearts of fools it is made known.

Even a fool, when he keeps silent, is considered wise;
When he closes his lips, he is considered prudent.

But the things that proceed out of the mouth come from the heart, and those defile the man.
