Philadelphia of the Decapolis (The other Philadelphia in New Testament times) and Rabbah of the Ammonites (Old Testament).

Amman, The capital of Jordan, derives its name from the 13th century BC when the "Ammonites" named it "Rabbath Ammon" with the term Rabbath meaning the "Capital" or the "King's Quarters". Over time, the term "Rabbath" was no longer used and the city became known as "Ammon". The influence of new civilizations that conquered the city gradually changed its name to "Amman". In the Hebrew Bible, it is referred to as "Rabbat ?Ammon" (Tiberian Hebrew Rabba? ?Amm?n). However, Ptolemy II Philadelphus, the Macedonian ruler of the Ptolemaic Kingdom who reigned from 283 to 246 BC, renamed the city to "Philadelphia" (Ancient Greek: Φιλαδ?λφεια; literally: "brotherly love") after occupying it. The name was given as an adulation to his own nickname, Philadelphus.
