Satan

Satan (Hebrew: שָּׂטָן satan, meaning "adversary";Arabic: شيطان shaitan, meaning; "astray", "distant", or sometimes "devil") is a figure appearing in the texts of the Abrahamic religions who brings evil and temptation, and is known as the deceiver who leads humanity astray. Some religious groups teach that he originated as an angel who fell out of favor with God, seducing humanity into the ways of sin, and who has power in the fallen world. In the Hebrew Bible and the New Testament, Satan is primarily an accuser and adversary, a decidedly malevolent entity, also called the devil, who possesses demonic qualities.

In Theistic Satanism, Satan is considered a positive force and deity who is either worshipped or revered. In LaVeyan Satanism, Satan is regarded as holding virtuous characteristics.

Judaism

Hebrew Bible

The original Hebrew term satan is a noun from a verb meaning primarily "to obstruct, oppose", as it is found in Numbers 22:22, 1 Samuel 29:4, Psalms 109:6.Ha-Satan is traditionally translated as "the accuser" or "the adversary". The definite article ha- (English: "the") is used to show that this is a title bestowed on a being, versus the name of a being. Thus, this being would be referred to as "the satan".
