• noun Synonyms Prophet, Seer, Soothsayer. A prophet is properly one who discloses or speaks forth to others the will of God; a seer is one who has himself learned God's will by a vision. Both titles were applied in the Old Testament to the same class of men, but at different times. The extra-Biblical uses of the words correspond to the Biblical. The word prophet is sometimes used in the Bible of a candidate for the prophetic office, or of an inspired preacher or interpreter. Soothsayer, as used in the Bible, implies imposture, and in other literature its standing is little better.
