'Border' in the Bible

The border of Amorite territory ran from the Scorpion Ascent to Sela and on up.

When the three hundred men blew their trumpets, the Lord caused the Midianites to attack one another with their swords throughout the camp. The army fled to Beth Shittah on the way to Zererah. They went to the border of Abel Meholah near Tabbath.

Then Israel went through the desert and bypassed the land of Edom and the land of Moab. They traveled east of the land of Moab and camped on the other side of the Arnon River; they did not go through Moabite territory (the Arnon was Moab's border).
