Final answer:
An oracle was a divine message generally delivered by a designated intermediary, not strictly by prophets, in various ancient cultures.
Step-by-step explanation:
An oracle was indeed a message from a deity or supernatural source, but it was not necessarily delivered to prophets specifically. In many ancient cultures, oracles were received by specially appointed spokespersons such as the priestesses of Apollo at Delphi in ancient Greece, who were not termed prophets. Hence, the statement that an oracle was a message from god delivered to one of his spokespersons, the prophets, is partially true; prophets could be recipients of divine messages, but they were not the only individuals who could receive oracles.
