After an earthquake in Judaea, the Nabateans rebelled and invaded Israel, but Herod at once crossed the Jordan river to Philadelphia (modern Amman) and both sides set up camp. The Nabataeans under Elthemus refused to give battle, so Herod forced the issue when he attacked their camp. A confused mass of Nabataeans gave battle but were defeated. Once they had retreated to their defences, Herod laid siege to the camp and over time some of the defenders surrendered. The remaining Nabataean forces offered 500 talents for peace, but this was rejected. Lacking water, the Nabataeans were forced out of their camp for battle, but were defeated in this last battle.
