3 Kings (1 Kings) 6:2
kg1 6:2THE BUILDING OF SOLOMON'S TEMPLE. (Kg1 6:1-4)
the house which king Solomon built for the Lord--The dimensions are given in cubits, which are to be reckoned according to the early standard (Ch2 3:3), or holy cubit (Eze 40:5; Eze 43:13), a handbreadth longer than the common or later one. It is probable that the internal elevation only is here stated.
3 Kings (1 Kings) 6:3
kg1 6:3the porch--or portico, extended across the whole front (see on Ch2 3:4).
3 Kings (1 Kings) 6:4
kg1 6:4windows of narrow lights--that is, windows with lattices, capable of being shut and opened at pleasure, partly to let out the vapor of the lamps, the smoke of the frankincense, and partly to give light [KEIL].
3 Kings (1 Kings) 6:5
kg1 6:5THE CHAMBERS THEREOF. (Kg1 6:5-10)
against the wall of the house he built chambers--On three sides, there were chambers in three stories, each story wider than the one beneath it, as the walls were narrowed or made thinner as they ascended, by a rebate being made, on which the beams of the side floor rested, without penetrating the wall. These chambers were approached from the right-hand side, in the interior of the under story, by a winding staircase of stone, which led to the middle and upper stories.
3 Kings (1 Kings) 6:7
kg1 6:7there was neither hammer nor axe nor any tool of iron heard in the house while it was in building--A subterranean quarry has been very recently discovered near Jerusalem, where the temple stones are supposed to have been hewn. There is unequivocal evidence in this quarry that the stones were dressed there; for there are blocks very similar in size, as well as of the same kind of stone, as those found in the ancient remains. Thence, probably, they would be moved on rollers down the Tyropean valley to the very side of the temple [PORTER, Tent and Kahn].
3 Kings (1 Kings) 6:9
kg1 6:9built the house--The temple is here distinguished from the wings or chambers attached to it--and its roofing was of cedar-wood.
3 Kings (1 Kings) 6:10
kg1 6:10chambers . . . five cubits high--The height of the whole three stories was therefore about fifteen cubits.
they rested on the house with timber of cedar--that is, because the beams of the side stones rested on the ledges of the temple wall. The wing was attached to the house; it was connected with the temple, without, however, interfering injuriously with the sanctuary [KEIL].
3 Kings (1 Kings) 6:11
kg1 6:11GOD'S PROMISES UNTO IT. (Kg1 6:11-14)
the word of the Lord came to Solomon--probably by a prophet. It was very seasonable, being designed: first, to encourage him to go on with the building, by confirming anew the promise made to his father David (Sa2 7:12-16); and secondly, to warn him against the pride and presumption of supposing that after the erection of so magnificent a temple, he and his people would always be sure of the presence and favor of God. The condition on which that blessing could alone be expected was expressly stated. The dwelling of God among the children of Israel refers to those symbols of His presence in the temple, which were the visible tokens of His spiritual relation to that people.
3 Kings (1 Kings) 6:15
kg1 6:15THE CEILING AND ADORNING OF IT. (Kg1 6:15-22)
he built the walls of the house within--The walls were wainscotted with cedar-wood; the floor, paved with cypress planks; the interior was divided (by a partition consisting of folding doors, which were opened and shut with golden chains) into two apartments--the back or inner room, that is, the most holy place, was twenty cubits long and broad; the front, or outer room, that is, the holy place, was forty cubits. The cedar-wood was beautifully embellished with figures in relievo, representing clusters of foliage, open flowers, cherubims, and palm trees. The whole interior was overlaid with gold, so that neither wood nor stone was seen; nothing met the eye but pure gold, either plain or richly chased.
3 Kings (1 Kings) 6:31
kg1 6:31for the entering of the oracle--The door of the most holy place was made of solid olive tree and adorned with figures. The door of the holy place was made of cypress wood, the sides being of olive wood.
3 Kings (1 Kings) 6:36
kg1 6:36the inner court--was for the priests. Its wall, which had a coping of cedar, is said to have been so low that the people could see over it.
3 Kings (1 Kings) 6:37
kg1 6:37THE TIME TAKEN TO BUILD IT. (Kg1 6:37-38)
In the fourth year was the foundation laid--The building was begun in the second month of the fourth year and completed in the eighth month of the eleventh year of Solomon's reign, comprising a period of seven and a half years, which is reckoned here in round numbers. It was not a very large, but a very splendid building, requiring great care, and ingenuity, and division of labor. The immense number of workmen employed, together with the previous preparation of the materials, serves to account for the short time occupied in the process of building.
