The name Wadi Musa means Valley of Moses in Arabic. It was reported that prophet Moses passed through the valley and struck water from the rock for his followers at the site of (Ain Musa) Moses water Spring (Moses’s Well). The Nabateans built channels that carried water from this spring to the city of Petra. Wadi Musa was also nicknamed the Guardian of Petra. Aaron, the brother of Moses, was buried in the nearby Mount Hor.
