'Fortifications' in the Bible

Is the land they live in good or bad? Are the cities they live in encampments or fortifications?

Foreigners lose heartand come trembling from their fortifications.

He strengthened their fortifications and put leaders in them with supplies of food, oil, and wine.

Foreigners lose heartand come trembling from their fortifications.

the roar of battle will rise against your people,and all your fortifications will be demolishedin a day of war,like Shalman’s destruction of Beth-arbel.Mothers will be dashed to piecesalong with their children.

One who scatters is coming up against you.Man the fortifications!Watch the road!Brace yourself!Summon all your strength!
