Barnes' Notes on the Whole Bible

The first three verses form part of the narrative commenced at 1 Chronicles 15:25. Compare 2 Samuel 6:17-19, where the passage is not torn from its proper context.

The rest ... - Rather, “the rest of the chosen ones, who were mentioned by name.” The “chosen ones” were “mentioned by name” in 1 Chronicles 15:17-24. A portion of them, namely, those named in 1 Chronicles 16:5-6, conducted the service in Jerusalem; the remainder were employed in the worship at Gibeon.
