Albert Barnes Commentary Numbers 34:16-29

"And Jehovah spake unto Moses, saying, These are the names of the men that shall divide the land unto you for inheritance: Eleazar the priest, and Joshua the son of Nun. And ye shall take one prince of every tribe, to divide the land for inheritance. And these are the names of the men: Of the tribe of Judah, Caleb the son of Jephunneh. And of the tribe of the children of Simeon, Shemuel the son of Ammihud. Of the tribe of Benjamin, Elidad the son of Chislon. And of the tribe of the children of Dan a prince, Bukki the son of Jogli. Of the children of Joseph: of the tribe of the children of Manasseh a prince, Hanniel the son of Ephod. And of the tribe of the children of Ephraim a prince, Kemuel the son of Shiphtan. And of the tribe of the children of Zebulun a prince, Elizaphan the son of Parnach. And of the tribe of the children of Issachar a prince, Paltiel the son of Azzan. And of the tribe of the children of Asher a prince, Ahihud the son of Shelomi. And of the tribe of the children of Naphtali a prince, Pedahel the son of Ammihud. These are they whom Jehovah commanded to divide the inheritance unto the children of Israel in the land of Canaan." — Numbers 34:16-29 (ASV)

Of the representatives previously selected through Moses, who were all princes, that is, heads of chief families in their respective tribes , Caleb alone, from the tribe of Judah, is also known to us (see Numbers 13:4 and following).

The order in which the tribes are named is peculiar to this passage. If they are taken in pairs—Judah and Simeon, Benjamin and Dan, Manasseh and Ephraim, Zebulun and Issachar, Asher and Naphtali—the order of these pairs agrees with the order in which their allotments in the Holy Land, also taken in pairs, followed one another on the map from south to north.
