Despite the compliance of Aretas, in 62 BCE Scaurus marched on Petra. However, a combination of the rough terrain and low supplies, obliged Scaurus to seek the aid of Hyrcanus, now High Priest (not king) of Judea, who sent Antipater to barter for peace with Aretas. The siege was lifted in exchange for several hundred talents of silver (to Scaurus himself) and recognition of Roman supremacy over Nabatea. Aretas would retain all Nabataean territory and possessions, becoming a vassal of the Roman Empire.
