Sihon, according to the Old Testament, was an Amorite king, who refused to let the Israelites pass through his country. The Bible describes that as the Israelites in their Exodus came to the country east of the Jordan, near Heshbon, King Siḥon of the Amorites refused to let them pass through his country. The Israelites fought Amorites in a battle, gaining complete victory. His walled towns were captured and the complete Amorite country was taken by the Israelites, who killed the king and "all his people." ( , ).
- "But Israel put them to the sword and took possession of their land, from the Arnon to the Jabbok, as far as [Az] of the Ammonites." ( )
In a similar way the Israelites took the country of Og, and these two victories gave them possession of the complete country east of the Jordan, from the Arnon to the foot of the Hermon. These victories, among the earliest successful campaigns of the Israelites, quickly became legendary among them, and are referred to numerous times in the Bible as prototypical examples of God-given victory.
