John Gill Commentary Joshua 15:56

"and Jezreel, and Jokdeam, and Zanoah," — Joshua 15:56 (ASV)

And Jezreel
This Jezreel in the tribe of Judah is different from that which was once a royal seat of some of the kings of Israel, and from which the famous valley of Jezreel or Esdraelon had its name: of this we have no other account elsewhere;

and Jokdeam ;
of which we have no other mention;

and Zanoah
is a distinct place from the city of the same name in the valley, (Joshua 15:34) .
