Note 1 at Acts 16:16: The Greek word used for soothsaying is the word "manteuomai" meaning to divine, practice divination. This is the only time it is used in the New Testament. It differs from sorcery in the sense that soothsaying is fortune telling while sorcery is all forms of witchcraft in the casting of spells and the using of drugs, potions, charms, amulets, etc..

This soothsaying would correspond to all the ungodly ways people seek to predict the future today, such as: horoscopes, reading of tea leaves and tarot cards etc., palm readers, crystal balls and on and on. This girl who did these things was demon possessed and so are those who claim to have these powers today.
