The King’s Highway was a trade route of vital importance to the ancient Middle East. It began in Egypt, and stretched across the Sinai Peninsula to Aqaba. From there it turned northward, leading to Damascus and the Euphrates River. The Highway is referred to in Numbers 20:17-21: Many of the wars of the Israelites against the kingdoms of the trans-Jordanian highlands during the period of the Kingdom of Israel (and its sister-kingdom, the Kingdom of Judah) probably were at least partly over control of the Highway.
