Belial

Belial (Hebrew beliyya'al, meaning worthlessness or without profit) is used throughout the Old Testament as a term for wickedness or wickedness personified, often translated worthless men or sons of Belial in the Authorized Version. It denotes moral depravity and rebellion against God: the men who demanded the gang-rape at Gibeah (Judges 19:22), the wicked sons of Eli (1 Samuel 2:12), and Nabal (1 Samuel 25:17) are all called sons of Belial. In the New Testament (2 Corinthians 6:15) Paul uses Belial as a proper name for Satan, asking what harmony Christ can have with Belial—making the term fully personalized as the embodiment of evil in contrast to Christ.
