Numbers 34:18

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

tn This sense is created by repetition: “one leader, one leader from the tribe.”

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.
