1 Chronicles 9:19-22

19Shallum the son of Kore, the son of Ebiasaph, the son of Korah, and his relatives of his father’s house, the Korahites, were in charge of the work of the service, doorkeepers of the Tent; and their fathers had been in charge of the camp of the Lord, keepers of the entrance.

20Phinehas the son of Eleazar was ruler over them in times past, and the Lord was with him.

21Zechariah son of Meshelemiah was gatekeeper at the entrance of the Tent of Meeting.

22All those chosen to be gatekeepers at the thresholds were 212. They were enrolled by their genealogies in their villages [around Jerusalem], these men [whose grandfathers] David and Samuel the seer had appointed to their official duty.
