³¹ The mouth of the righteous bringeth forth wisdom; But the perverse tongue shall be cut off.

³⁰ The mouth of the righteous talketh of wisdom, And his tongue speaketh justice.

¹⁸ Let the lying lips be dumb, Which speak against the righteous insolently, With pride and contempt.

¹¹ But the king shall rejoice in God: Every one that sweareth by him shall glory; For the mouth of them that speak lies shall be stopped. Psalm 64 For the Chief Musician. A Psalm of David.

³ What shall be given unto thee, and what shall be done more unto thee, Thou deceitful tongue?

⁴ Sharp arrows of the mighty, With coals of juniper.

¹¹ The mouth of the righteous is a fountain of life; But violence covereth the mouth of the wicked.

²⁰ The tongue of the righteous is `as' choice silver: The heart of the wicked is little worth.

²¹ The lips of the righteous feed many; But the foolish die for lack of understanding.
