Post Reply - Satanism & Hebrew-ism

So since i know Hebrew and a lot of stuff about the bible and so on ( i am not religious )
I noticed that a lot of satanistic symbols or black metal album covers with Hebrew letters , and a lot of people think that judaism is somehow related to satanism . I saw a pentagram and the letters - ל ו י ת ן - written on it ( which means Leviathan the beast of evil as i understand ) and another cover with some nonsense in Hebrew too.
But the relation is not true because satan doesn't even exist in the bible as we know it , satan was invented in the Christianity. But my question - What is the connection between the two ? why do i see a lot of use of it ?
I am just curious to know.
