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 comments on Joshua 13:9];

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