'Islands' in the Bible

Then he will turn his attention to the coasts and islands and capture many. But a commander will put an end to his taunting; instead, he will turn his taunts against him.

because ships will come against him from the Mediterranean islands. Disheartened, he'll return, incited to vehemence against the holy covenant, and he'll take action. As he returns, he'll show deference to those who abandon the holy covenant.
