What is Judaism's view on magic?

Answer 1

Magic as a stage entertainment is fine; however, the belief in sorcery and witchcraft was forbidden in The Bible. Despite his ban of such things, King Saul consults the Witch of Endor before a battle. She conjures the spirit of the Judge Samuel, who tells Saul he will die in the forthcoming struggle.

Eventually, witchcraft would be considered a capital offense.

Answer 2

In Judaism, engaging in seances, conjuring, spells, magic, sorcery, divination (etc.), are all strictly forbidden (Deuteronomy ch.18).Even as stage-entertainment, magic may not be presented mysteriously.
Such paranormal occurrences as true prophecy and miracles are achieved through life-long service of God, and are in any case not believed to have happened in the last 2300 years.
