Chose a man of integrity and feared God more than most people do

Nehemiah 7:1-3
I put in charge of Jerusalem my brother Hanani, along with Hananiah the commander of the citadel(堡壘), because he was a man of integrity and feared God more than most people do.
I said to them, “The gates of Jerusalem are not to be opened until the sun is hot. While the gatekeepers are still on duty, have them shut the doors and bar them. Also appoint residents of Jerusalem as guards, some at their posts and some near their own houses.”
The work completed, orders given and duties assigned.
Why?
Orders given and duties assigned is necessary to maintain a city or a company.
Assigned a commander of citadel, he is a man of integrity and feared God more than most people do. Nehemiah chose a mam who are integrity and fear the Lord, Integrity means he is honest to God and to his duty. Fear the Lord means he is doing the righteous things.
Appoint residents of Jerusalem as guards, some at their posts and some near their own houses. It is a good idea for there were not many resident and chose those who near their own houses is easy and not much burden to them.
Good leader and have a rule to do is needed.
How?
Chose a good leader and make a simple rule to follow is a good way to them and to many tasks.
