The "witch of En-dor" ( 1 Samuel 28 ) was a necromancer, i.e., one who feigned to hold converse with the dead. The damsel with "a spirit of divination" ( Acts 16:16 ) was possessed by an evil spirit, or, as the words are literally rendered, "having a spirit, a pithon." The reference is to the heathen god Apollo, who was regarded as the god of prophecy.
