Joshua 13:8

8 with which lineage(s) Reuben, and Gad, wielded the land, which land Moses, the servant of the Lord, gave to them beyond the flowings of (the) Jordan, at the east coast; (For the tribes of Reuben, and Gad, and the eastern half of the tribe of Manasseh, took the land, which land Moses, the servant of the Lord, gave them beyond the flowings of the Jordan River, on the east side;)

Joshua 13:8 Meaning and Commentary

Joshua 13:8

With whom the Reubenites and the Gadites have received their
inheritance
That is, along with the half tribe of Manasseh, but not with that half of it before mentioned, who was to haven division of a part with the nine tribes, but with the other half of the tribe settled beyond Jordan; with them the tribes of Reuben and Gad had received their portion at their own request, and so were to have no share in the present distribution:

which Moses gave them beyond Jordan eastward;
at their desire, ( Numbers 32:1-5 ) , and upon certain conditions to be performed by them, ( Numbers 32:20-23 ) ;

[even] as Moses the servant of the Lord gave them;
this character of Moses, as the "servant of the Lord", seems to be observed to show that he gave the said tribes their inheritance: according to the will of God, and in obedience to it: here end the words of the Lord to Joshua, and next follows an account of the land given to the two tribes and a half described by the writer of this book.

Joshua 13:8 In-Context

6 of all men that dwelled in the hill, from the Lebanon till to the waters of Misrephothmaim, and all men of Sidon; I am, that shall do away them from the face of the sons of Israel; therefore come it into the part of (the) heritage of Israel, as I commanded to thee. (of all those who live in the hill country, from Lebanon unto Misrephothmaim, and all those of Sidon; I am he, who shall do them away from before the Israelites; and so divide it all up for the inheritance of the Israelites, as I commanded to thee.)

7 And thou now part the land into (a) possession to the nine lineages, and to the half lineage of Manasseh, (And now divide thou up the land for a possession for the nine tribes, and for the western half of the tribe of Manasseh.)

8 with which lineage(s) Reuben, and Gad, wielded the land, which land Moses, the servant of the Lord, gave to them beyond the flowings of (the) Jordan, at the east coast; (For the tribes of Reuben, and Gad, and the eastern half of the tribe of Manasseh, took the land, which land Moses, the servant of the Lord, gave them beyond the flowings of the Jordan River, on the east side;)
