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 9 during altar work and prayers to protect a client from enemies and to bring the punishment of the Lord upon them. This Psalm is employed by rootworkers to bring swift retribution against an enemy if they are guilty. Psalm 9 is also used by hoodoo conjure doctors to make a charm to restore the health of male children. In addition this Psalm may be used in court cases where there is a need to influence a judge or jury by turning aside the testimony of a hostile enemy witness.
To the chief Musician upon Muthlabben, A Psalm of David.
 I will praise thee, O LORD, with my whole heart; I will shew forth all thy marvellous works.
 I will be glad and rejoice in thee: I will sing praise to thy name, O thou most High.
 When mine enemies are turned back, they shall fall and perish at thy presence.
 For thou hast maintained my right and my cause; thou satest in the throne judging right.
 Thou hast rebuked the heathen, thou hast destroyed the wicked, thou hast put out their name for ever and ever.
 O thou enemy, destructions are come to a perpetual end: and thou hast destroyed cities; their memorial is perished with them.
 But the LORD shall endure for ever: he hath prepared his throne for judgment.
 And he shall judge the world in righteousness, he shall minister judgment to the people in uprightness.
 The LORD also will be a refuge for the oppressed, a refuge in times of trouble.
 And they that know thy name will put their trust in thee: for thou, LORD, hast not forsaken them that seek thee.
 Sing praises to the LORD, which dwelleth in Zion: declare among the people his doings.
 When he maketh inquisition for blood, he remembereth them: he forgetteth not the cry of the humble.
 Have mercy upon me, O LORD; consider my trouble which I suffer of them that hate me, thou that liftest me up from the gates of death:
 That I may shew forth all thy praise in the gates of the daughter of Zion: I will rejoice in thy salvation.
 The heathen are sunk down in the pit that they made: in the net which they hid is their own foot taken.
 The LORD is known by the judgment which he executeth: the wicked is snared in the work of his own hands. Higgaion. Selah.
 The wicked shall be turned into hell, and all the nations that forget God.
 For the needy shall not alway be forgotten: the expectation of the poor shall not perish for ever.
 Arise, O LORD; let not man prevail: let the heathen be judged in thy sight.
 Put them in fear, O LORD: that the nations may know themselves to be but men. Selah.
