John Gill Commentary Joshua 13:33

"But unto the tribe of Levi Moses gave no inheritance: Jehovah, the God of Israel, is their inheritance, as he spake unto them." — Joshua 13:33 (ASV)

But unto the tribe of Levi Moses gave not [any] inheritance ,
&c.] Neither on the other side Jordan, nor did he order them any in Canaan; but expressly declared they were to have no part in the division of it, though they were his own tribe; which shows him to be a disinterested man, that he faithfully observed the orders and instructions the Lord gave him:

the Lord God of Israel [was] their inheritance, as he said unto them ;
what was given to the Lord out of the sacrifices, and the tithes, and firstfruits, that were theirs; see (Numbers 18:20–32) (Deuteronomy 18:1–8) .
