How to say "city wall, rampart" in Arabic

Modern Hebrew's word for a city wall is חומה, unrelated to سور. But biblical Hebrew has a tantalizing, disputed cousin: Genesis 49:22 reads עֲלֵי־שׁוּר, traditionally rendered '[a fruitful bough] by a wall' — a שׁוּר some scholars connect to Akkadian šūru and Arabic sūr 'wall', though others read that שור as 'a wild colt' or 'a spring'. Take the link as a hedge, not a certainty.
