“King Jotham built the upper gate of the house of Yahweh. He did extensive building on the wall of Ophel. Moreover he built cities in the hill country of Judah. He built forts and towers on the wooded hills.”
Nevertheless, King Jotham did put a gate on the house of Yahweh, the Temple. He also built up the wall or the slope or the Ophel that the Temple sat on. He also did some building in the hill country of Judah, with forts and towers.
