John Gill Commentary Ezekiel 12:4

"And thou shalt bring forth thy stuff by day in their sight, as stuff for removing; and thou shalt go forth thyself at even in their sight, as when men go forth into exile." — Ezekiel 12:4 (ASV)

Then will you bring forth your stuff by day in their sight ,
&c.] Bring it forth, that they may be spectators of it; and "by day", that it might be manifest to them what was carried out; and this day by day, till all was removed: as stuff for removing ;
that is intended to be removed from one place to another, and is carried away in the daytime, in the view of everyone: and you will go forth at even in their sight ;
as a man, having removed his goods in the daytime, goes forth himself at evening: this denotes the flight of Zedekiah from Jerusalem in the night, (Jeremiah 39:4) ; as they that go forth into captivity :
with a sorrowful countenance, in a mournful habit, and with airs and gestures showing anger, anxiety, and distress; with a bundle on their shoulders, and a staff in their hands.
