Sihon — striking down. The whole country on the east of Jordan, from the Arnon to the Jabbok, was possessed by the Amorites, whose king, Sihon, refused to permit the Israelites to pass through his territory, and put his army in array against them. The Israelites went forth against him to battle, and gained a complete victory. The Amorites were defeated; Sihon, his sons, and all his people were smitten with the sword, his walled towns were captured, and the entire country of the Amorites was taken possession of by the Israelites (Num. 21:21–30; Deut. 2:24–37).
The country from the Jabbok to Hermon was at this time ruled by Og, the last of the Rephaim. He also tried to prevent the progress of the Israelites, but was utterly routed, and all his cities and territory fell into the hands of the Israelites (comp. Num. 21:33–35; Deut. 3:1–14; Ps. 135:10–12; 136:17–22).
These two victories gave the Israelites possession of the country on the east of Jordan, from the Arnon to the foot of Hermon. The kingdom of Sihon embraced about 1,500 square miles, while that of Og was more than 3,000 square miles.
