John Gill Commentary Ezekiel 48:33

"And at the south side four thousand and five hundred [reeds] by measure, and three gates: the gate of Simeon, one; the gate of Issachar, one; the gate of Zebulun, one." — Ezekiel 48:33 (ASV)

Ver. 33 And at the south side four thousand and five hundred measures ,
&c.] The south side of the city measured just the same as the north and east sides did: and three gates ;
were on that side, as on the others: one gate of Simeon, one gate of Issachar, one gate of Zebulun ;
at which these tribes entered, or those they represent.
