angel thrust back his sword into the sheath. He continued to sacrifice there, saying, "This is the house of the Lord God, and this is the altar of the burnt-offering for Israel[178]." From the above narrative we see that the threshing-floor was without the city, and the property of a Jebusite, that it was a sacred spot, chosen by the Lord himself for his House, and identical with Moriah. Josephus[179] informs us that this was the very place to which Abraham brought his son Isaac to offer him as a burnt-offering. Here it will be well to digress a little to describe a 'threshing-floor' (Goren) of this period. It consisted of a plot of ground, usually rocky, levelled to allow of the crops being spread out to the air and sun, ready for the labourers, yet so situated as to be sheltered from the full force of the prevailing wind. For greater security it was usually near a dwelling; and, either within the enclosure or in the immediate neighbourhood, cisterns were hewn in the rock, some to catch the rain-water, others to hold the grain and other farm produce[180]. The purposes for which these were designed can be determined from their form. Those for water have only one chamber, with a shaft (about 2-3/4 feet wide) opening out into the middle of the roof; the rest have two chambers, one below the other, communicating by a hole (about 4 feet wide) in the middle of the floor of the upper[181], which itself opens to the threshing-floor by a sloping passage (about 3-1/2 feet wide). The lower cavern is deeper and larger than the upper. I have met with very many of these cisterns during my frequent journeys in Palestine, where they are still applied to their ancient uses; they are especially common in those Arab villages which stand upon sites mentioned in the Bible; as at Beth-shemesh, on the road from Jaffa to Jerusalem just at the east of the village of _El-Atrun_, at _Neby Samwîl_ (formerly Ramah the home of Samuel), at Gibeon and Beth-horon, at _Beit-zacaria_, the ancient Bath-zacharias[182], at _El-Kebab_ in the plain of Sharon, and in many other places. In the threshing-floor of Araunah there are many cisterns, but I wish to call especial attention to two very near each other, to the north of the _Kubbet-es-Sakharah_[183] and to one inside it, beneath the sacred rock; of which the visitor can only see the hole on the north-east side and the upper part, but can convince himself by the hollow sound of the existence of the lower cave. These are, in my opinion, the strongest proofs of the identity of the position of the mosque and its platform with the ancient threshing-floor of the Jebusite. I will hereafter explain how I contrived to explore the interior of the cisterns in a place of such sanctity.
