Albert Barnes Commentary Joshua 21:1

"Then came near the heads of fathers` [houses] of the Levites unto Eleazar the priest, and unto Joshua the son of Nun, and unto the heads of fathers` [houses] of the tribes of the children of Israel;" — Joshua 21:1 (ASV)

A list of the Levitical cities, varying in some particulars from that given in this chapter, is also given in 1 Chronicles 6:54–81.
