'Coast land' in the Bible

The coastland peoples spread out into their lands. These are Japheth’s sons by their clans, in their nations. Each group had its own language.

And the inhabitants of this coastland will say on that day, ‘Look, this is what has happened to those we relied on and fled to for help to rescue us from the king of Assyria! Now, how will we escape?’”

Mourn, inhabitants of the coastland,you merchants of Sidon;your agents have crossed the sea

Cross over to Tarshish;wail, inhabitants of the coastland!

The coastland will belongto the remnant of the house of Judah;they will find pasture there.They will lie down in the eveningamong the houses of Ashkelon,for the Lord their God will return to themand restore their fortunes.
