The name 'Heman' is a Jewish name, meaning 'Faithfull'. You will find it approximately 10 times in the bible (eg. see: [1]) It is held that Heman is another name for Moses. The Psalm written by Heman seems to have been written in a state of despair. According to Martin Marty, a professor of church history at the University of Chicago, Psalm 88 is “a wintry landscape of unrelieved bleakness.” Psalm 88 ends by saying: You have taken my companions and loved ones from me; the darkness is my closest friend. (Psalm 88:18, NIV).
