The importance of the solar cult at Heliopolis is reflected in both ancient pagan and current monotheistic beliefs. Egyptian and Greco-Roman mythology held that the bennu or phoenix brought the ashes of its predecessor to the altar of the sun god at Heliopolis each time it was reborn. In the Hebrew's scriptures, Heliopolis is referenced directly and obliquely, usually in reference to its prominent pagan cult. In his prophesies against Egypt, Isaiah claimed the "City of the Sun" ("Ir ha Shemesh") would be one of the five Egyptian cities to follow the Lord of Heaven's army and speak Hebrew. Jeremiah and Ezekiel mention the "House of the Sun" ("Beth Shemesh") and Ôn, claiming Nebuchadnezzar of Babylon would shatter its obelisks and burn its temple and that its "young men of Folly" ("Aven") would "fall by the sword".
