2 Chronicles 33:13-14

13When Manasseh prayed to the Lord, the Lord answered him. He was kind to Manasseh, as Manasseh had asked him to be. So the Lord brought Manasseh back to Jerusalem again, to rule there as king. Then Manasseh knew that the Lord is the true God.

14After that, Manasseh repaired the outside wall of the City of David. He built it higher, from the west side of Gihon stream, as far as the Fish Gate. Then he continued around Ophel hill. He built the wall up higher than it had been. He also put army officers with their soldiers in all the strong cities of Judah.
