'Hostile' in the Bible

For a [pagan and hostile] nation has invaded My land [like locusts],Mighty and without number;Its teeth are the teeth of a lion,And it has the fangs of a lioness.

A day of darkness and gloom,A day of clouds and of thick [dark] mist,Like the dawn spread over the mountains;There is a [pagan, hostile] people numerous and mighty,The like of which has never been beforeNor will be again afterwardEven for years of many generations.
