'Edge' in the Bible

Gilead was living over Jordan; and Dan was waiting in his ships; Asher kept in his place by the sea's edge, living by his inlets.

And the three hundred gave a loud note on their horns, and every man's sword was turned by the Lord against his brother all through the army; and the army went in flight as far as Beth-shittah in the direction of Zeredah, to the edge of Abel-meholah by Tabbath.
