'Coast land' in the Bible

From these, [the people of] the coastlands of the nations were separated and spread into their lands, every one according to his own language, according to their constituent groups (families), and into their nations:

So the inhabitants of this coastland [the Israelites and their neighbors] will say in that day, ‘Look what has happened to those in whom we hoped and trusted and to whom we fled for help to be spared from the king of Assyria! But we, how will we escape [captivity and exile]?’”

Because of the day that is comingTo destroy all the PhilistinesAnd to cut off from Tyre and SidonEvery ally who remains.For the Lord is going to destroy the Philistines,The remnant [still surviving] of the coastland of Caphtor.
