Jerusalem is built like a city where everything is close together.
David moved into the fort. He called it the City of David. He built up the area around the fort. He filled in the low places. He started at the bottom and worked his way up.
So we rebuilt the wall. We repaired it until all of it was half as high as we wanted it to be. The people worked with all their heart.
The Lord builds up Jerusalem. He gathers the scattered people of Israel.
