From Association of Independent Readers and Rootworkers
Hoodoo psychic readers, spirit workers and root doctors who recite Psalms on behalf of clients may work with Psalm 12 for
altar work and prayers aimed at giving protection against enemies. When a client is feeling that they may be faced with severe persecution or oppression, this Psalm is recited to petition the Lord to provide protection. Psalm 12 is often employed by
hoodoo conjure workers in cases against the wicked and false.
To the chief Musician upon Sheminith, A Psalm of David.
 Help, LORD; for the godly man ceaseth; for the faithful fail from among the children of men.
 They speak vanity every one with his neighbour: with flattering lips and with a double heart do they speak.
 The LORD shall cut off all flattering lips, and the tongue that speaketh proud things:
 Who have said, With our tongue will we prevail; our lips are our own: who is lord over us?
 For the oppression of the poor, for the sighing of the needy, now will I arise, saith the LORD; I will set him in safety from him that puffeth at him.
 The words of the LORD are pure words: as silver tried in a furnace of earth, purified seven times.
 Thou shalt keep them, O LORD, thou shalt preserve them from this generation for ever.
 The wicked walk on every side, when the vilest men are exalted.
