Joshua 13:14

14.Only unto the tribe of Levi, etc This exception was also necessary, lest the Levites might allege that they were unjustly disinherited, and thus excite great commotions in regard to their right. He therefore reminds them that Moses was the author of this distinction, and, at the same time, shows that they have no reason to complain of having been in any way defrauded, because an excellent compensation was given them. For although the sacrifices were not equally divided among the Levites, their subsistence was sufficiently provided for by all the first-fruits and the tithes. Moreover, as God allures them by hire to undertake the charge of sacred things, so he exhorts the people in their turn to be faithful in paying the sacred oblations by declaring that their sacrifices are the maintenance of the Levites.
