1 Chronicles 9:18-19

18Prior to this time, they were responsible for the King’s Gate on the east side. These men served as gatekeepers for the camps of the Levites.

19Shallum was the son of Kore, a descendant of Abiasaph, from the clan of Korah. He and his relatives, the Korahites, were responsible for guarding the entrance to the sanctuary, just as their ancestors had guarded the Tabernacle in the camp of the Lord.
