1 Chronicles 23:28 Meaning and Commentary

1 Chronicles 23:28

things, and the work of the service of the house of God;
to keep the house, and all the apartments in it, courts and chambers, clean, by sweeping and washing them, and carrying out all the filth thereof made by the sacrifices, and otherwise.
