What is the devil's name?
The devil is called by
different names. One is Satan, a Hebrew word meaning "Opponent" or "Enemy" (Job 1:6-12; 2:1-6; Zecharia 3:1-2; Revelation 12:10). In Greek his name is "Diabolo" meaning "Slanderer". He is also symbolicly called "the Great Dragon" (Revelation 12:9) or the "Old Serpent" (snake) referring to the form in which he appeared to Eve in Eden (Genesis 3).
In Matthew 12:24 we hear about Beelzebub, but it is believed that he was the head of the devils who possessed the people of those times. The devil is also called "a murderer from the beginning" and "a liar and the father of lies" (John 8:44).
