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 11 for
altar work and prayers aimed at saving the client from persecution. This Psalms is employed by rootworkers to cast off evil and fear. Psalm 11 is a plea to the Lord to help protect the client from being beset by enemies and foes. Root doctors pray this Psalm to rain down the retribution against the wicked. Therefore this Psalms is employed on behalf of righteous clients.
To the chief Musician, A Psalm of David.
 In the LORD put I my trust: How say ye to my soul, Flee as a bird to your mountain?
 For, lo, the wicked bend their bow, they make ready their arrow upon the string, that they may privily shoot at the upright in heart.
 If the foundations be destroyed, what can the righteous do?
 The LORD is in his holy temple, the LORD's throne is in heaven: his eyes behold, his eyelids try, the children of men.
 The LORD trieth the righteous: but the wicked and him that loveth violence his soul hateth.
 Upon the wicked he shall rain snares, fire and brimstone, and an horrible tempest: this shall be the portion of their cup.
 For the righteous LORD loveth righteousness; his countenance doth behold the upright.
