¹¹ A fountain of life is a mouth of righteousness,
    and a mouth of wickedness conceals violence.

¹³ On the lips of one who has understanding, wisdom is found,
    but a rod is for the back of one who lacks sense.^[a]

¹⁴ Those who are wise lay up knowledge,
    but to the mouth of the fool, ruin draws near.

²⁰ Choice silver is a tongue of righteousness,
    a heart^[a] of wickedness is of little worth.^[b]
21 Lips of righteousness feed many,
    but fools die for lack of sense.^[c]

³¹ The mouth of the righteous brings forth wisdom,
    but a tongue of perversity will be cut off.
³² The lips of the righteous know the acceptable,
    but the mouth of the wicked, the perverse.
