1 Chronicles 9:17-22

17And the doorkeepers: Shallum, and Akkub, and Talmon, and Ahiman, and their brethren; Shallum was the chief.

18And they have been hitherto in the king's gate eastward: they were the doorkeepers in the camps of the children of Levi.

19And Shallum the son of Kore, the son of Ebiasaph, the son of Korah, and his brethren, of the house of his father, the Korahites, were over the work of the service, keepers of the thresholds of the tent, and their fathers, set over the camp of Jehovah, were keepers of the entrance.

20And Phinehas the son of Eleazar was the ruler over them formerly; Jehovah was with him.

21Zechariah the son of Meshelemiah was doorkeeper at the entrance to the tent of meeting.

22All these chosen to be doorkeepers at the thresholds were two hundred and twelve. These were registered by genealogy according to their villages: David and Samuel the seer had instituted them in their trust.
