John Gill Commentary Numbers 36:2

"and they said, Jehovah commanded my lord to give the land for inheritance by lot to the children of Israel: and my lord was commanded by Jehovah to give the inheritance of Zelophehad our brother unto his daughters." — Numbers 36:2 (ASV)

And they said
One in the name of the rest:

the Lord commanded my lord ;
that is, Moses, whom they address in a very respectable manner, being the chief governor of the nation under God:

to give the land for an inheritance by lot to the children of Israel ;
which command may be seen, in (Numbers 26:53–56) :

and my lord was commanded by the Lord to give the inheritance of
Zelophehad our brother ;
or kinsman, being of the same tribe:

unto his daughters ;
who sued for it, and upon Moses's consulting the Lord about it, it was ordered they should have it, (Numbers 27:1–11) and which these princes observed was likely to be attended with the following inconvenience.
