CATHOLIC ENCYCLOPEDIA: Belial: "Belial
Found frequently as a personal name in the Vulgate and various English translations of the Bible, is commonly used as a synonym of Satan, or the personification of evil. This sense is derived from II Cor., vi, 15, where Belial (or Beliar) as prince of darkness is contrasted with Christ, the light. It is clear in the Vulgate and Douay translations of III Kings, xxi, 10 and 13, where the same Hebrew word is rendered once as Belial and twice as 'the devil'.

In Ps., sviii, 5, it is parallel to 'death' and 'Sheol'; some understand it as 'destruction', Cheyne as 'the abyss'.

Belial, from meaning wickedness or Sheol, could develop into a name for the prince of evil or of darkness; and as such was widely used at the beginning of our era. Under the names Beliar, Be"
