This is the account of the forced labor that King Solomon imposed to build the house of the LORD, his own palace, the supporting terraces, and the wall of Jerusalem, as well as Hazor, Megiddo, and Gezer.

As soon as Pharaoh’s daughter had come up from the City of David to the palace that Solomon had built for her, he built the supporting terraces.

and this is the account of his rebellion against the king. Solomon had built the supporting terraces and repaired the gap in the wall of the city of his father David.

He built up the city around it, from the supporting terraces to the surrounding wall, while Joab restored the rest of the city.

Then Hezekiah worked resolutely to rebuild all the broken sections of the wall and to raise up towers on it. He also built an outer wall and reinforced the supporting terraces of the City of David, and he produced an abundance of weapons and shields.
