For the length of the chambers that were in the utter court was fifty cubits,.... Which was the reason why the wall was of the same length, that it might be answerable to them; here length is put for breadth; see Eze 42:2, this measure was from the north to south, as Lipman observes:and lo, before the temple were an hundred cubits; as the breadth of the wall and chambers was fifty, so in length, as they were over against the temple, they were an hundred cubits, as in Eze 42:2, unless the account is to be taken thus; that the row of chambers towards the north were fifty cubits long, and the row towards the south over against the other was fifty cubits, and so both made a hundred; to which sense is the Septuagint version,"for the length of the chambers that look to the outward court was fifty cubits, and those (that is, those that looked to the temple, or were before that) answered to them, the whole a hundred cubits;''that is, both rows made a hundred cubits; but rather, as Lipman says, the chambers contained from east to west a hundred cubits.
