Nehemiah 7:3-4 ESV
And I said to them, “Let not the gates of Jerusalem be opened until the sun is hot. And while they are still standing guard, let them shut and bar the doors. Appoint guards from among the inhabitants of Jerusalem, some at their guard posts and some in front of their own homes.” The city was wide and large, but the people within it were few, and no houses had been rebuilt.
