Joshua 13:16

And their coast was from Aroer that is on the bank of the river Arnon ,.... As the country of Sihon is described, Joshua 13:9 ; from whence it appears that it was his country which was given to Reuben, though not all of it:

and the city that is in the midst of the river ; See Gill on Joshua 13:9 ,

and all the plain by Medeba ; which reached unto Dibon, Joshua 13:9 .
