Deuteronomy 3:16 Meaning and Commentary

Deuteronomy 3:16

And unto the Reubenites, and unto the Gadites
The tribes of Reuben and Gad:

I gave from Gilead even unto the river Arnon:
see ( Deuteronomy 3:12 )

half the valley and the border;
or rather half the river, the river Arnon; and so it is rendered "the middle of the river", in ( Joshua 12:2 ) and so here the middle of the torrent by the Vulgate Latin and Septuagint versions, and by Onkelos:

even unto the river Jabbok, which is the border of the children of
Ammon;
beyond which the land given to the tribes of Reuben and Gad reached not; see ( Deuteronomy 2:37 ) .
