Jerusalem is built to be a city where the people are united.
David lived in the fortress and called it the City of David. He built the city ⌞of Jerusalem⌟ around it from the Millo to the palace.
The Lord is the builder of Jerusalem. He is the one who gathers the outcasts of Israel together.
So we rebuilt the wall, which was rebuilt to about half its ⌞original⌟ height. The people worked with determination.
