1 Chronicles 26:12-19

12Of these were the courses of the doorkeepers, even of the chief men, having offices like their brethren, to minister in the house of Jehovah. 13And they cast lots, as well the small as the great, according to their fathers’ houses, for every gate. 14And the lot eastward fell to Shelemiah. Then for Zechariah his son, a discreet counsellor, they cast lots; and his lot came out northward. 15To Obed-edom southward; and to his sons the store-house. 16To Shuppim and Hosah westward, by the gate of Shallecheth, at the causeway that goeth up, watch against watch. 17Eastward were six Levites, northward four a day, southward four a day, and for the store-house two and two. 18For Parbar westward, four at the causeway, and two at Parbar. 19These were the courses of the doorkeepers; of the sons of the Korahites, and of the sons of Merari.
