In this verse, the words wall and bar are singular in form, but they refer to all the walls and bars of these cities as a group. If it would be helpful in your language, you could use plural forms. Alternate translation: [with walls and bars of bronze]

and,bar[s]_of (Some words not found in UHB: son_of Geber_(1127) in,Ramoth- -gilˊād to=him/it villages_of Yāʼīr/(Jair) son_of Mənashsheh which/who [are]_in,Gilead to=him/it region_of ʼArgoⱱ which/who [is]_in,Bashan sixty cities great walls and,bar[s]_of copper/brass/bronze//coin )

When the author notes that the gates of these cities each had a bar of bronze, he is indicating that these bronze bars made the gates very difficult to break through. You could include this information if that would be helpful to your readers. Alternate translation: [and gates that the people could make very secure, since they had bronze bars]
