And all the cities of the plain
 In the champaign country, as well as those in the mountainous part: 
 and all the kingdom of Sihon;
 or, as Masius renders the words, "which all had been the kingdom of Sihon"; for the whole kingdom of Sihon was not given to Reuben, only a part of it, and the rest to Gad, as in ( Joshua 13:27 ) ; 
 king of the Amorites, which reigned in Heshbon;
 as in ( Joshua 13:10 ) ; 
 whom Moses smote with the princes of Midian, Evi, and Rekem, and Zur,
 and Hur, and Reba;
 not at the same time that Sihon was smitten by him, but afterwards in a war with Midian, ( Numbers 31:8 ) ; where their names are given as here; and there they are called kings of Midian, petty kings, and, as it seems by what follows, were subject to Sihon, and therefore are here mentioned: 
 [which were] dukes of Sihon dwelling in the country;
 for Midian, as Kimchi supposes, and not without reason, was under the government of Sihon, and these were his nobles, though they dwelt in the land of Midian.
