'Walls' in the Bible

All of these [were] fortified towns with high walls, gates, and bars, {apart from} very many [of] the villages of the open country.

"Hear, Israel, you [are] about to cross the Jordan today to go to dispossess nations larger and more numerous than you, great cities fortified {with high walls},

And it shall besiege you in all your towns {until your high and fortified walls fall}, which you [are] trusting in {throughout your land}; and it shall besiege you in all of your towns in all of your land that Yahweh your God has given to you.
