Deuteronomy 2:26 - Joseph Benson’s Commentary on the Old and New Testaments

I sent messengers unto Sihon To show the prince of the Amorites that we were not aggressors, and offered no violence, and that, if he refused to grant us a passage through his land, his destruction would be of himself. Kedemoth was a city of that tract which fell to the lot of the Reubenites.
