1 Kings 6:5

Against the wall — The beams of the chambers were not fastened into the wall, but leaned upon the buttresses of the wall. Chambers — For the laying the priests garments, and other utensils belonging to the temple, therein. Round about — On all the sides except the east, where the porch was; and except some very small passages for the light. And yet these lights might be in the five uppermost cubits of the wall, which were above all these chambers, for these were only fifteen cubits high, and the wall was twenty cubits high. Chambers — Galleries which encompassed all the chambers; and which were necessary for passage to them.
