John Gill Commentary 1 Chronicles 9:5

"And of the Shilonites: Asaiah the first-born, and his sons." — 1 Chronicles 9:5 (ASV)

And of the Shilonites
Not called so from the city of Shiloh, which was in Ephraim; whereas these here intended were of the tribe of Judah, and were either the descendants of a man whose name was Shiloni, (Nehemiah 11:5) or rather these are the same with the Shelanites, (Numbers 26:20) so called from Shelah the son of Judah; and so the Targum here is, ``and of the tribe of Shelah:'' Asaiah the firstborn, and his sons ;
the same with Maaseiah, (Nehemiah 11:5) .
