He built also the house of the forest of Libanus, the length of it was a hundred cubits, and the breadth fifty cubits, and the height thirty cubits: and four galleries between pillars of cedar: for he had cut cedar trees into pillars.

He built also the house of the forest of Lebanon; its length was a hundred cubits, and its breadth fifty cubits, and its hight thirty cubits, upon four rows of cedar pillars, with cedar beams upon the pillars.

And he buildeth the house of the forest of Lebanon; a hundred cubits is its length, and fifty cubits its breadth, and thirty cubits its height, on four rows of cedar pillars, and cedar-beams on the pillars;

And he made the house of the Woods of Lebanon, which was a hundred cubits long and fifty cubits wide and thirty cubits high, resting on four lines of cedar-wood pillars with cedar-wood supports on the pillars.

And he built the house from the forest of Lebanon: one hundred cubits in length, and fifty cubits in width, and thirty cubits in height, with four walkways between columns of cedar. For he had hewn the cedar trees into columns.

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.

The house of the forest of Lebanon - It was not built in Lebanon, but is thought to have been on Mount Sion. And why it was called the house of the forest of Lebanon does not appear; probably it was because it was built almost entirely of materials brought from that place. See the following verses.

He built also the house (b) of the forest of Lebanon; the length thereof [was] an hundred cubits, and the breadth thereof fifty cubits, and the height thereof thirty cubits, upon four rows of cedar pillars, with cedar beams upon the pillars.
(b) Because of the beauty of the place, and great abundance of cedar trees that went into the building of it, it was compared to mount Lebanon.

He built also the house of the forest of Lebanon,.... Besides the temple, his own palace, and the queen's; so called, not because it was built on Mount Lebanon, which lay at the northern border of the land, at a great distance from Jerusalem, whereas this was both a magazine of arms, and a court of judicature, 1-Kings 7:7; see 1-Kings 10:17; neither of which can be supposed to be far from Jerusalem; but because not only it was built of the cedars of Lebanon, but in a situation, and among groves of trees which resembled it; it seems to have been a summer house; and so the Targum calls it, a royal house of refreshment:
the length thereof was an hundred cubits, and the breadth thereof fifty and the height thereof thirty cubits; so that it was in every measure larger than the temple; and, there was good reason for it, since into that only the priests entered; whereas into this went not only Solomon's family but his courtiers and nobles, and all foreign ambassadors, and whoever had any business with him, which required various rooms to receive them in:
upon four rows of cedar pillars; or piazzas:
with cedar beams upon the pillars; which laid the floor for the second story.

OF THE HOUSE OF LEBANON. (1-Kings 7:2-7)
He built also the house of the forest of Lebanon--It is scarcely possible to determine whether this was a different edifice from the former, or whether his house, the house of the forest of Lebanon, and the one for Pharaoh's daughter, were not parts of one grand palace. As difficult is it to decide what was the origin of the name; some supposing it was so called because built on Lebanon; others, that it was in or near Jerusalem, but contained such a profuse supply of cedar columns as to have occasioned this peculiar designation. We have a similar peculiarity of name in the building called the East India house, though situated in London. The description is conformable to the arrangement of Eastern palaces. The building stood in the middle of a great oblong square, which was surrounded by an enclosing wall, against which the houses and offices of those attached to the court were built. The building itself was oblong, consisting of two square courts, flanking a large oblong hall which formed the center, and was one hundred cubits long, by fifty broad. This was properly the house of the forest of Lebanon, being the part where were the cedar pillars of this hall. In front was the porch of judgment, which was appropriated to the transaction of public business. On the one side of this great hall was the king's house; and on the other the harem or royal apartments for Pharaoh's daughter (Esther 2:3, Esther 2:9). This arrangement of the palace accords with the Oriental style of building, according to which a great mansion always consists of three divisions, or separate houses--all connected by doors and passages--the men dwelling at one extremity, the women of the family at the other, while public rooms occupy the central part of the building.

Of the forest of Lebanon - An house so called, because it was built in the forest of Lebanon, for a summer - seat, whither Solomon, having so many chariots and horses, might at any time retire with ease. The length - Of the principal mansion; to which doubtless other buildings were adjoining. Pillars - Upon which the house was built, and between which there were four stately walks. Beams - Which were laid for the floor of the second story.
