Tombs of the Prophets

The Tomb of the Prophets Haggai, Zechariah and Malachi lit. 'Graves the Prophets'; Hebrew: מערת הנביאים "Cave of the Prophets") is an ancient burial site located on the upper western slope of the Mount of Olives, Jerusalem. According to a medieval Jewish tradition also adopted by Christians, the catacomb is believed to be the burial place of Haggai, Zechariah and Malachi, the last three Hebrew Bible prophets who are believed to have lived during the 6th–5th centuries BC. Archaeologists have dated the three earliest burial chambers to the first century BC, thus contradicting the tradition.
