11  The mouth of the righteous ^xis a fountain of life,

but the mouth of the wicked conceals violence.

13  On the lips of him who has understanding, wisdom is found,

but ^aa rod is for the back of him who lacks sense.

14  The wise lay up knowledge,

^bbut the mouth of a fool brings ruin near.

20  The tongue of the righteous is ^kchoice silver;

the heart of the wicked is of little worth.

21  The lips of the righteous feed many,

but fools die for lack of sense.

31  ^sThe mouth of the righteous brings forth wisdom,

but the ^tperverse tongue will be cut off.

32  The lips of the righteous know what is acceptable,

but the mouth of the wicked, what is perverse.
