Belial

Belial, or, more accurately, Beli'al, a Hebrew word, often treated by the translators of the authorised version as a proper name, but really an abstract term meaning 'that which is without use or profit,' 'worthlessness,' hence 'wickedness.' It is mostly used in the forms 'son of Belial,' 'man of Belial;' but the adjunct is often omitted, and the word stands by itself as a term of reproach.
