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 134 during
altar work and prayers for matters of higher education. Psalm 134 is used by spirit workers as a prayer for success in matters of school. This Psalm is especially potent for matters dealing with higher education, like college and can be used to help the client excell in their examinations and courses. Many root doctors will recite Psalm 134 daily before attended classes.
 Behold, bless ye the LORD, all ye servants of the LORD, which by night stand in the house of the LORD.
 Lift up your hands in the sanctuary, and bless the LORD.
 The LORD that made heaven and earth bless thee out of Zion.
