'Coast' in the Bible

Also Judah took Gaza with the coast thereof, and Askelon with the coast thereof, and Ekron with the coast thereof.

And the coast of the Amorites was from the going up to Akrabbim, from the rock, and upward.

But Sihon trusted not Israel to pass through his coast: but Sihon gathered all his people together, and pitched in Jahaz, and fought against Israel.
