2CH 16:1

1 When Asa had been ruling [Judah] for almost 36 years, King Baasha of Israel went [with his army] to attack Judah. They [captured the town of] Ramah [north of Jerusalem] and started to build a wall around [it], in order to prevent any people from entering or leaving the area in Judah that was ruled by King Asa [because the only road into Judah from Israel went through Ramah].
