Ophel
The Ophel , also Graecised to Ophlas, the biblical name apparently given to a certain part of a settlement or city that is elevated from its surroundings, probably means fortified hill or risen area. In the Hebrew Bible the Ophel refers to a specific part in two cities: the extended City of David (the oldest part of Jerusalem), as in the Book of Chronicles and the Book of Nehemiah , and at Samaria, the ancient capital of the Kingdom of Israel, mentioned in the Second Book of Kings . The Mesha Stele is the only extra-biblical source using the word, also in connection to a fortified area.
