'Rampart' in the Bible

All of the men who had accompanied Joab arrived and besieged Sheba in Abel of Beth-maacah. They threw up a siege ramp against the city rampart and began to batter the wall to demolish it.

You are to lay siege against it, build a rampart around it, set a bulwark against it, encircle it with a berm, set up camps against it, and place battering rams around it.

After this, you are to turn toward the rampart of Jerusalem and oppose it with your bare arms, because I'm going to prophesy about it.

You are being attacked by advancing forces! Guard your rampart! Watch your roads! Prepare yourselves! Marshall your defenses!

I myself will be an encircling rampart of fire,' declares the LORD, "and I will be the glory in her midst.'
