Proverbs 10:6, 8, 10-11, 13-14, 18-21, 31-32

Blessings are on the head of the righteous, but the mouth of the wicked conceals violence.

The wise of heart will receive commandments, but a babbling fool will come to ruin.

Whoever winks the eye causes trouble, and a babbling fool will come to ruin. The mouth of the righteous is a fountain of life, but the mouth of the wicked conceals violence.

On the lips of him who has understanding, wisdom is found, but a rod is for the back of him who lacks sense. The wise lay up knowledge, but the mouth of a fool brings ruin near.

The one who conceals hatred has lying lips, and whoever utters slander is a fool. When words are many, transgression is not lacking, but whoever restrains his lips is prudent. The tongue of the righteous is choice silver; the heart of the wicked is of little worth. The lips of the righteous feed many, but fools die for lack of sense.

The mouth of the righteous brings forth wisdom, but the perverse tongue will be cut off. The lips of the righteous know what is acceptable, but the mouth of the wicked, what is perverse.
