1 Chronicles 9:19

Keepers of the gates of the tabernacle; or, who were, to wit, in time past, which is expressed in a like case, 1 Chronicles 9:20, when the tabernacle was standing, before the temple was built. Their fathers; the Kohathites, of whom see on Numbers 4:4. Over the host of the Lord, or, with (as this Hebrew particle is oft used) the host, &c., i.e. when the Israelites were in the wilderness, encamped in a military manner round about the tabernacle, with or among whom these were then placed. Keepers of the entry, i.e. of the veil by which they entered into the tabernacle; which he calls the entry distinctively, because then there were no gates. The meaning is, that all things were now restored to their primitive order and institution; and the several persons took those places and offices upon them, which their ancestors had before them.
