1 Chronicles 9:19

19 Shallum (son of Kore, grandson of Ebiasaph, great-grandson of Korah) and the members of his family (Korah's descendants) were responsible for serving as watchmen at the entrances to the tent, as their ancestors had been in charge of guarding the entrances to the LORD's camp.

1 Chronicles 9:19 Meaning and Commentary

1 Chronicles 9:19

And Shallum the son of Kore
The same as in ( 1 Chronicles 9:17 ) whose pedigree is traced up to Ebiasaph the son of Korah, see ( Exodus 6:24 )

and his brethren, of the house of his father, the Korahites;
so called, because they descended from Korah:

[were over] the work of the service, keepers of the gates of the
tabernacle;
until the temple was built:

and their fathers being over the host of the Lord;
the Levites, who were the Lord's army, and whose service is represented as a warfare, ( Numbers 4:5 )

[were] keepers of the entry;
into the tabernacle, that none might enter that were impure; or into the court of the priests, excepting priests; or into the holiest of all, as Kimchi suggests.
