The New John Gill Exposition of the Entire Bible1 Chronicles 9:25
And their brethren, which were in their villages…
Assigned them to dwell in:
were to come after seven days from time to time with them;
there was a
new course of them every week; the old ones went off of duty, and
another course succeeded, which came out of the villages where they
dwelt, and the old course retired to theirs.
