'Mainland' in the Bible

and her villages on the mainland will be slaughtered by the sword. Then they will know that I am Yahweh.”

He will slaughter your villages on the mainland with the sword. He will set up siege works against you, and will build a ramp and raise a wall of shields against you.

Also they will take your riches as spoil and plunder your merchandise, and tear down your walls and your pleasant houses, and throw your stones and your timber and the debris [from your city] out in the water.
