Charles Ellicott Commentary 1 Kings 7:8-11

"And his house where he was to dwell, the other court within the porch, was of the like work. He made also a house for Pharaoh`s daughter (whom Solomon had taken to wife), like unto this porch. All these were of costly stones, even of hewn stone, according to measure, sawed with saws, within and without, even from the foundation unto the coping, and so on the outside unto the great court. And the foundation was of costly stones, even great stones, stones of ten cubits, and stones of eight cubits. And above were costly stones, even hewn stone, according to measure, and cedar-wood." — 1 Kings 7:8-11 (ASV)

The residence of the king, and the separate palace for the queen, distinct from the apartments of the inferior wives and concubines, are not described; except that they lay “within the porch,” that is, in the rear in another court, and were of “like work.” This is further explained by saying that they had costly stones of great size in the foundation, and stones above, hewn and sawn from top to bottom, carefully finished on the outside towards the great court, as well as on the inside, and were in all cases roofed with cedar.

Josephus tells us that the inner court was adorned with trees and fountains, and had colonnades round it; and gives an enthusiastic description of the internal decoration of the rooms, panelled up to a certain height with polished marble, with a band of highly-wrought metal-work of foliage of all kinds above this, and the rest of the wall up to the ceiling plastered and painted in colors (ceiled with cedar, and painted with vermilion.Jeremiah 22:14). This description is curiously confirmed and illustrated by some of the recent discoveries at Nineveh.
