1 Chronicles 26:12-19

12These divisions of the gatekeepers, through their leaders, had duties for ministering in the temple of the Lord, just as their relatives had. 13Lots were cast for each gate, according to their families, young and old alike. 14The lot for the East Gate fell to Shelemiah. Then lots were cast for his son Zechariah, a wise counselor, and the lot for the North Gate fell to him. 15The lot for the South Gate fell to Obed-Edom, and the lot for the storehouse fell to his sons. 16The lots for the West Gate and the Shalleketh Gate on the upper road fell to Shuppim and Hosah. Guard was alongside of guard: 17There were six Levites a day on the east, four a day on the north, four a day on the south and two at a time at the storehouse. 18As for the court to the west, there were four at the road and two at the court itself. 19These were the divisions of the gatekeepers who were descendants of Korah and Merari.
