I Chronicles 9:17-22

And the gatekeepers were Shallum, Akkub, Talmon, Ahiman, and their brethren. Shallum was the chief. Until then they had been gatekeepers for the camps of the children of Levi at the King’s Gate on the east. Shallum the son of Kore, the son of Ebiasaph, the son of Korah, and his brethren, from his father’s house, the Korahites, were in charge of the work of the service, gatekeepers of the tabernacle. Their fathers had been keepers of the entrance to the camp of the LORD. And Phinehas the son of Eleazar had been the officer over them in time past; the LORD was with him. Zechariah the son of Meshelemiah was keeper of the door of the tabernacle of meeting. All those chosen as gatekeepers were two hundred and twelve. They were recorded by their genealogy, in their villages. David and Samuel the seer had appointed them to their trusted office.
