John Calvin Commentary Joshua 13:24

"And Moses gave unto the tribe of Gad, unto the children of Gad, according to their families." — Joshua 13:24 (ASV)

And Moses gave inheritance unto the tribe of Gad, etc. The observation made above also applies to the tribe of Gad, namely, that their legitimate boundaries were carefully defined to prevent disputes regarding their possession. Meanwhile, God is extolled for His generosity in having expelled nations of great renown and substituted them in their place.

This is expressed more clearly concerning the half-tribe of Manasseh, when sixty cities are enumerated as included in their inheritance. Therefore, it is also evident that Moses was not generous by mistake, because it was well known to God how many cities He was giving them out of His boundless generosity.

In a short clause, the tribe of Levi is again excluded, so that the Levites would not be able in the future to pretend that the grant which the Reubenites, Gadites, and the half-tribe of Manasseh had obtained without the casting of lots, also belonged to them in common; for they are expressly forbidden to share with their brothers. This made it easy for them to shrewdly interpret, for their own advantage, that they were entitled to share with others. Here, however, it is not the sacrifices, as mentioned a little earlier, but God Himself who is said to be their inheritance; if they are not satisfied with Him, they only convict themselves of excessive pride and insufferable fussiness.
