'Enemy's' in the Bible

"How long must I see the enemy's battle flags and hear the military signals of their bugles?"

The snorting of the enemy's horses is already being heard in the city of Dan. The sound of the neighing of their stallions causes the whole land to tremble with fear. They are coming to destroy the land and everything in it! They are coming to destroy the cities and everyone who lives in them!"

This is what the Lord says:Keep your voice from weepingand your eyes from tears,for the reward for your work will come—this is the Lord’s declaration—and your children will return from the enemy’s land.

You must not say, 'No, we will not stay. Instead we will go and live in the land of Egypt where we will not face war, or hear the enemy's trumpet calls, or starve for lack of food.'
