To Shuppim and Hosah westward, by the gate of Shallecheth, at the causeway that goeth up, watch against watch. Eastward were six Levites, northward four a day, southward four a day, and for the store-house two and two. For Parbar westward, four at the causeway, and two at Parbar. These were the courses of the doorkeepers; of the sons of the Korahites, and of the sons of Merari.
