Thematic Bible: They served in twenty-four courses

They cast lots according to their ancestral houses, young and old alike, for each gate. The lot for the east [gate] fell to Shelemiah. They also cast lots for his son Zechariah, an insightful counselor, and his lot came out for the north [gate]. Obed-edom's was the south [gate], and his sons' [lot] was the storehouses; read more.
for Shuppim and Hosah it was the west [gate] and the gate of Shallecheth on the ascending highway. There were guards stationed at every watch. There were six Levites each day on the east, four each day on the north, four each day on the south, and two pair at the storehouses. As for the court on the west, there were four at the highway and two at the court. Those were the divisions of the gatekeepers from the sons of the Korahites and Merarites.
