1 Chronicles 26:13-19

They cast lots, the small (younger) and great (older) alike, in accordance with their fathers’ households, for every gate. The lot for the east [gates] fell to Shelemiah. They cast lots also for his son Zechariah, a wise counselor, and his lot came out for the north [gates]. To Obed-edom [it came out] for the south [gates], and the storehouse was allotted to his sons. To Shuppim and Hosah [the lot fell] for the west [gates], by the gate of Shallecheth, on the ascending highway, division by division. On the east were six Levites, on the north four a day, on the south four a day, and two by two at the storehouse. At the colonnade on the west side [of the outer court of the temple] there were four at the road and two at the colonnade. These were the divisions of the gatekeepers among the Korahites and the sons of Merari.
