The second choir went north along the western wall, passing:
The Broad Wall (Nehemiah 3:8)
The Old City Gate (Nehemiah 3:6)
The Fish Gate (Nehemiah 3:3)
They continued along the northern side of the wall until they reached the Sheep Gate (Nehemiah 3:1) at the northeast corner of the temple.
The Guard Gate might be the Inspection Gate (Nehemiah 3:31).
