“Jonathan took up residence in Jerusalem. He began to rebuild and restore the city. He directed those who were doing the work to build the walls and encircle Mount Zion with squared stones, for better fortification. They did this.”
Now Jonathan moved to Jerusalem, when he had lived at Michmash. He began to rebuild and restore the city. He wanted to encircle Mount Zion that is Jerusalem with square stones to make a better fortification of the city since the 10 year old King Antiochus V and Lysias had torn down the walls in chapter 6 of this book. This is much like Nehemiah, chapters 2 and 3, who rebuilt Jerusalem.
