'Border' in the Bible

The border of the Amorites ran from the ascent of Akrabbim, from Sela (rock) and upward.

When Gideon’s men blew the three hundred trumpets, the Lord set the sword of one [Midianite] against another even throughout the whole army; and the army fled as far as Beth-shittah toward Zererah, as far as the border of Abel-meholah, by Tabbath.
