Following are a number of back-translations as well as a sample translation for translators of Joshua 13:21:

• Kupsabiny: “It included all the cities in that raised area and all the cities which king Sihon that king of the Amorites who ruled from Heshbon ruled. Moses defeated that king and the leaders of Midian who lived in that country. Those leaders were: Evi, Rekem, Zur, Hur and Reba who (plur.) had made an alliance with Sihon.” (Source: Kupsabiny Back Translation)

• Hiligaynon: “and all the towns/cities of the valley/plain and all the towns/cities which are-under-the-jurisdiction of Sihon the king of the Amornon who reigned in Heshbon. He was-defeated by Moises as-well-as the kings of Midian who were Evi, Rekem, Zur, Hur, and Reba. (This they)/These reigned in their lands under the ruling of King Sihon.” (Source: Hiligaynon Back Translation)
