'Coastline' in the Bible

Ashdod and its towns and villages, Gaza and its towns and villages as far as the River of Egypt, and the coastline of the Mediterranean Sea.

He rebuilt Israel's coastline from the entrance of Hamath as far as the Sea of the Arabah, in accordance with the message from the LORD God of Israel that he spoke through his servant Jonah the prophet, Amittai's son, who was from Gath-hepher.

this is what the Lord GOD says: "Look out! I'm raising my clenched fist in Philistia's direction. I'm going to execute the Cherethites and destroy what's left of the coastline of the Mediterranean Sea.
