Numbers 34:18

34:18 You must take one leader from every ¹  tribe to assist in allocating the land as an inheritance. ² 

Numbers 35:31

35:31 Moreover, you must not accept a ransom for the life of a murderer who is guilty of death; he must surely be put to death.

[34:18]  ¹ tn This sense is created by repetition: “one leader, one leader from the tribe.”

[34:18]  ² tn The sentence simply uses לִנְחֹל (linkhol, “to divide, apportion”). It has been taken already to mean “allocate as an inheritance.” Here “assist” may be added since Joshua and Eleazar had the primary work.
