1 Kings 6:8 - Joseph Benson’s Commentary on the Old and New Testaments

The door for the middle chamber That is, by which they entered to go up into the middle row of chambers; was in the right side That is, in the south side, called the right side, because, when a man looks toward the east, the south is on his right hand. There was another door on the left, or the north side, leading to the chambers on that side. They went up with winding stairs Without the wall, leading up to the gallery, out of which they went into the several chambers. Into the middle chamber Or, rather, into the middle story, or row of chambers; and so in the following words, out of the middle story: for these stairs could not lead up into each of the chambers, nor was it needful, but only into the story, which was sufficient for the use of all the chambers.
