'Fortified' in the Bible

Where can we go? Our brothers have discouraged us, saying: The people are larger and taller than we are; the cities are large, fortified to the heavens. We also saw the descendants of the Anakim there.’

All these were fortified with high walls, gates, and bars, besides a large number of rural villages.

“Listen, Israel: Today you are about to cross the Jordan to go and drive out nations greater and stronger than you, with large cities fortified to the heavens.

They will besiege you within all your gates until your high and fortified walls, that you trust in, come down throughout your land. They will besiege you within all your gates throughout the land the Lord your God has given you.
