Early witches were people who practiced witchcraft, using magic spells and calling upon spirits for help or to bring about change. Most witches were thought to be pagans doing the Devil's work. Many, however, were simply natural healers or so-called "wise women" whose choice of profession was misunderstood.
It's unclear exactly when witches came on the historical scene, but one of the earliest records of a witch is in the Bible in the book of 1 Samuel, thought be written between 931 B.C. and 721 B.C. It tells the story of when King Saul sought the Witch of Endor to summon the dead prophet Samuel's spirit to help him defeat the Philistine army.
The witch roused Samuel, who then prophesied the death of Saul and his sons. The next day, according to the Bible, Saul's sons died in battle, and Saul committed suicide.
Other Old Testament verses condemn witches, such as the oft-cited Exodus 22:18, which says, "thou shalt not suffer a witch to live." Additional Biblical passages caution against divination, chanting or using witches to contact the dead.
