These are the divisions of the gatekeepers:
From the Korahites, there was Meshelemiah son of Kore, of the family of Abiasaph. 1 2 The sons of Meshelemiah were Zechariah (the oldest), Jediael (the second), Zebadiah (the third), Jathniel (the fourth), 3 Elam (the fifth), Jehohanan (the sixth), and Eliehoenai (the seventh). 4 The sons of Obed-edom, also gatekeepers, were Shemaiah (the oldest), Jehozabad (the second), Joah (the third), Sacar (the fourth), Nethanel (the fifth), 5 Ammiel (the sixth), Issachar (the seventh), and Peullethai (the eighth). God had richly blessed Obed-edom. 6 Obed-edom’s son Shemaiah had sons with great ability who earned positions of great authority in the clan. 7 Their names were Othni, Rephael, Obed, and Elzabad. Their relatives, Elihu and Semakiah, were also very capable men. 8 All of these descendants of Obed-edom, including their sons and grandsons - sixty-two of them in all - were very capable men, well qualified for their work.
9 Meshelemiah’s eighteen sons and relatives were also very capable men.
10 Hosah, of the Merari clan, appointed Shimri as the leader among his sons, though he was not the oldest. 11 His other sons included Hilkiah (the second), Tebaliah (the third), and Zechariah (the fourth). Hosah’s sons and relatives, who served as gatekeepers, numbered thirteen in all.
These divisions of the gatekeepers were named for their family leaders, and like the other Levites, they served at the house of the Lord .
They were assigned by families for guard duty at the various gates, without regard to age or training, for it was all decided by means of sacred lots.
The responsibility for the east gate went to Meshelemiah 2 and his group. The north gate was assigned to his son Zechariah, a man of unusual wisdom.
The south gate went to Obed-edom, and his sons were put in charge of the storehouse.
Shuppim and Hosah were assigned the west gate and the gateway leading up to the Temple. 3 Guard duties were divided evenly.
Six Levites were assigned each day to the east gate, four to the north gate, four to the south gate, and two pairs at the storehouse.
Six were assigned each day to the west gate, four to the gateway leading up to the Temple, and two to the courtyard. 4
These were the divisions of the gatekeepers from the clans of Korah and Merari.
