“And it came to pass, as we went to prayer, a certain damsel possessed with a spirit of divination met us, which brought her masters much gain by soothsaying:”
King James Version (KJV)
Ac 16:16 As we went to prayer. To the place of prayer. A certain damsel possessed with a spirit of divination. Literally, "The spirit of a Pythoness". This meant, among the Greeks, a prophetic spirit, Pythias being one of the names of Apollo, the god of prophecy. The account shows (1) that the damsel was "possessed", (2) that her strange power gave her value in that it was superhuman, (3) that she was a slave, owned by several masters, and brought them "much gain by soothsaying". Luke does not say that she foretold the future, but the people thought she did. She was a demoniac. See PNT "Mt 8:29".
