John Gill Commentary Ezekiel 46:8

"And when the prince shall enter, he shall go in by the way of the porch of the gate, and he shall go forth by the way thereof." — Ezekiel 46:8 (ASV)

And when the prince shall enter, he shall go in by the way of
the porch of that gate (See Gill on Ezekiel 46:2); and he shall go forth by the way of it ;
the same way he came in, he shall go out; not so the people; and, to introduce the manner of their going in and out, this is repeated concerning the prince.
