Nehemiah 7:4

Now the city was large and great
The circumference of it, all within the wall; for that was built on its old foundation, and enclosed as much ground as ever it did: Hecataeus ^F2, an Heathen writer, says the circumference of Jerusalem was fifty furlongs, which was more than six miles; but Josephus ^F3 makes the circuit of it but thirty three furlongs or about six miles:

but the people were few therein;
in comparison of the largeness of the place; for though there were 42,360 that came up at first with Zerubbabel, and many more with Ezra, yet a great number chose to settle in the towns and cities in the country, Jerusalem being in such a desolate condition:

and the houses were not builded;
some were, but they were but few, many of them still lay in ruins.
