Ammon

Ammon is an ancient country in the Middle East. It was in northwestern Jordan and east of the Kingdom of Israel.
In the Bible it is often called the "Kingdom of Ammon".
Rabbath Ammon - present-day Amman - was its capital.
According to the Biblical Book of Genesis Ammon is a grandson of Lot, the nephew of Abraham (the other grandson is Moab; the Kingdom of Moab was south of Ammon).
The Ammonites often fought with the Israelites.
