The people were few - The number of those who returned with Zerubbabel was no more than 42,360 Nehemiah 7:66. Less than 2,000 people had come with Ezra Ezra 8:1-20.

The houses were not builded - The city was not yet rebuilt, only a row of houses in the inside of the wall all round.

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 (b), an Heathen writer, says the circumference of Jerusalem was fifty furlongs, which was more than six miles; but Josephus (c) 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.

Now the city was large and great--The walls being evidently built on the old foundations, the city covered a large extent of surface, as all Oriental towns do, the houses standing apart with gardens and orchards intervening. This extent, in the then state of Jerusalem, was the more observable as the population was comparatively small, and the habitations of the most rude and simple construction--mere wooden sheds or coverings of loose, unmortared stones.

The measures taken by Nehemiah for increasing the number of the inhabitants of Jerusalem. - Nehemiah 7:4 The city was spacious and great, and the people few therein, and houses were not built. ידים רחבת, broads on both sides, that is, regarded from the centre towards either the right or left hand. The last clause does not say that there were no houses at all, for the city had been re-inhabited for ninety years; but only that houses had not been built in proportion to the size of the city, that there was still much unoccupied space on which houses might be built.
