The Mouth, the Lips, the Tongue

 
11 The mouth of a righteous one [is] a fountain of life;
But the mouth of the wicked covereth violence.
12 Hatred stirreth up strifes;
But love covereth all transgressions.
13 In the lips of one intelligent wisdom is found;
But a rod [is] for the back of him that is void of understanding [or, heart].
14 The wise lay up knowledge;
But the mouth of the fool [is] near destruction.
