Another water source mentioned by al-Muqaddsi is Bir Ayub ('En Rogel), of which it is said that it is visited by the water of the Zamzam (the spring of life in Mecca) during the Hadj. `En Rogel is mentioned also in the Jerusalem guide of the Cairo Geniza (eleventh century) together with Hezekiah's Tunnel (Jerusalem guide, p. 75). According to a popular tradition Job drank from the spring water and was cured after bathing in it.
