'Fortified' in the Bible

Where are we going up? our brothers have made our heart to melt, saying, 'The people are greater and taller than we; the cities are great and fortified up to the sky; and moreover we have seen the sons of the Anakim there.'"

All these were cities fortified with high walls, gates, and bars; besides the unwalled towns a great many.

Hear, Israel: you are to pass over the Jordan this day, to go in to dispossess nations greater and mightier than yourself, cities great and fortified up to the sky,

They shall besiege you in all your gates, until your high and fortified walls come down, in which you trusted, throughout all your land; and they shall besiege you in all your gates throughout all your land, which Yahweh your God has given you.
