Therefore set I in the lower places behind the wall, and on the higher places, I even set the people after their families with their swords, their spears, and their bows.

I set the people in the place behind the wall round about in order, with their swords, and spears, and bows.

I set in the lower places behind the wall in exposed places, I even set the people, according to their families, with their swords, their spears and their bows.

And I appoint at the lowest of the places, at the back of the wall, in the clear places, yea, I appoint the people, by their families, with their swords, their spears, and their bows.

So in the lowest part of the space at the back of the walls, in the open places, I put the people by families, with their swords, their spears, and their bows.

So I stationed the people in order, in places behind the wall, all around it, with their swords, and lances, and bows.

The lower places - The places where those within the walls had the least advantage of elevation, the naturally weak places, where an enemy was likely to make his attack.

Therefore set I in the lower places behind the wall,.... Where the wall was lowest, and the enemy could more easily break it down, or get over it:
and on the higher places; where the wall was higher; or rather on the towers upon the walls, as the word signifies the tops of rocks, which are dry and smooth, see Ezekiel 24:2.
I even set the people after their families; according to their rank, number, strength, and valour:
with their swords, their spears, and their bows; with weapons they could use both near, and at a distance.

Nehemiah 4:7 is hardly intelligible. We translate it: Then I placed at the lowest places behind the wall, at the dried-up places, I (even) placed the people, after their families, with their swords, their spears, and their bows. למּקום מתּחתּיּות is a stronger expression for למּקום מתּחת when used to indicate position, and מן points out the direction. The sense is: at the lowest places from behind the wall. בּצּחחים gives the nature of the places where the people were placed with arms. צחיח and צחיחה mean a dry or bare place exposed to the heat of the sun: bare, uncovered, or empty places, perhaps bare hills, whence approaching foes might be discerned at a distance. The second ואעמיד is but a reiteration of the verb, for the sake of combining it with its object, from which the ואעמיד at the beginning of the verse was too far removed by the circumstantial description of the locality.
(Note: Bertheau considers the text corrupt, regarding the word מתּחתּיּות as the object of אעמיד, and alters it into מחשׁבות or חשּׁבנות, engines for hurling missiles (2-Chronicles 26:15), or into מטחיּות (a word of this own invention), instruments for hurling. But not only is this conjecture critically inadmissible, it also offers no appropriate sense. The lxx reads the text as we do, and merely renders בצחחיים conjecturally by ἐν τοῖς σκεπεινοῖς. Besides, it is not easy to see how חשׁבנות could have arisen from a false reading of מתחתיות; and it should be remembered that מחשׁבות does not mean a machine for hurling, while מטחתייות is a mere fabrication. To this must be added, that such machines are indeed placed upon the walls of a fortress to hurl down stones and projectiles upon assaulting foes, and not behind the walls, where they could only be used to demolish the walls, and so facilitate the taking of the town by the enemy.)

Behind - Within the walls where they were not yet raised to their due height, and therefore most liable to the enemies assault. Higher - Upon the tops of the walls where they were finished, and the towers which were built here and there upon the wall; whence they might shoot arrows, or throw stones.
