1 Chronicles 9:17-25

The security guards were Shallum, Akkub, Talmon, Ahiman, and their brothers. Shallum was the chief and up to now the security guard at the King’s Gate on the east. They also served as security guards at the camps of Levite families. Shallum son of Kore, the son of Ebiasaph, the son of Korah, along with his brothers in the Korahite family, were in charge of the services of worship as doorkeepers of the Tent, as their ancestors had guarded the entrance to the camp of God. In the early days, Phinehas son of Eleazar was in charge of the security guards—God be with him! Now Zechariah son of Meshelemiah was the security guard at the entrance of the Tent of Meeting. The number of those who had been chosen to be security guards was 212—they were officially registered in their own camps. David and Samuel the seer handpicked them for their dependability. They and their sons had the permanent responsibility for guarding the gates of God’s house, the house of worship; the main security guards were posted at the four entrances, east, west, north, and south; their brothers in the villages were scheduled to give them relief weekly—the four main security guards were responsible for round-the-clock surveillance.
