describes that as the Israelites
in their Exodus
came to the country east of the Jordan
, king Sihon of the Amorites
refused to let them pass through his country. The Israelites fought him in a battle, gaining complete victory. Sihon and his sons were put to the sword, his walled towns were captured and the complete Amorite country was taken by the Israelites. (Num. 21:21-30, Deut. 2:24-37).
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.
