Many have supposed that the buildings mentioned in 1 Kings 7:1-2, 1 Kings 7:8, were three entirely distinct and separate buildings. But it is perhaps best to consider the “house” of 1 Kings 7:1 as the palace proper - Solomon’s own dwelling-house (see 1 Kings 7:8); the house of 1 Kings 7:2, as the state apartments; and the house for Pharaoh’s daughter as the hareem or zenana; and to regard these three groups of buildings as distinct, though interconnected, and as together constituting what is else-where termed “the king’s house” 1 Kings 9:10.
The house of the forest of Lebanon - This name was probably given from the supposed resemblance of the mass of cedar pillars, which was its main feature, to the Lebanon cedar forest. Its length of “a hundred cubits,” or 150 feet, was nearly twice as long as the entire temple without the porch. Some of the great halls in Assyrian palaces were occasionally as much as 180 feet.
The breadth “of fifty cubits,” or 75 feet, is a breadth very much greater than is ever found in Assyria, and one indicative of the employment in the two countries of quite different methods of roofing. By their use of pillars the Jews, like the Persians, were able to cover in a very wide space.
Four rows - The Septuagint gives “three rows.” If the pillars were forty-five 1 Kings 7:3, fifteen in a row, there should have been but three rows, as seems to have been the case in the old palace of Cyrus at Pasargadae. If there were four rows of fifteen, the number of pillars should have been sixty.
