In almost every town in Judah, priests had been offering sacrifices to the LORD at local shrines. Josiah brought these priests to Jerusalem and had their shrines made unfit for worship--every shrine from Geba just north of Jerusalem to Beersheba in the south. He even tore down the shrine at Beersheba that was just to the left of Joshua Gate, which was named after the highest official of the city.
From Geba down to Rimmon south of Jerusalem, the entire country will be turned into flatlands, with Jerusalem still towering above. Then the city will be full of people, from Benjamin Gate, Old Gate Place, and Hananel Tower in the northeast part of the city over to Corner Gate in the northwest and down to King's Wine Press in the south. Jerusalem will always be secure and will never again be destroyed.
