Joshua 18:7

But the Levites have no part among you
And so needed not to send any men out of their tribe to measure the land on their account, and is a reason why the remaining part of the land was to be divided into seven parts only:

for the priesthood of the Lord [is] his inheritance;
not only the office, but what appertained to it, all the perquisites of it, the tithes, firstfruits, parts of the sacrifices see ( Joshua 13:14 ) ;

and Gad, and Reuben, and half the tribe of Manasseh, have received
their inheritance beyond Jordan on the east, which Moses the servant of
the Lord gave them;
and so had no share in the division of the land of Canaan, being sufficiently provided for.
