For the successful employment of such great numbers of workmen an effective system of organization was necessary; we are not surprised, therefore, in reading that thirty-three hundred overseers were in service. The efficiency of the system is attested by the success attending the great undertaking. The Israelites and the men of Tyre and Sidon worked in harmony, and much of the building material was shaped by pattern and measurement in forest and quarry; therefore "the house, when it was in building, was built of stone made ready before it was brought thither; so that there was neither hammer nor ax nor any tool of iron heard in the house, while it was in building."[38] Our primary source of information relating to the erection of the great Temple is the scriptural record contained in I Kings, chapters 6 and 7; a later account appears in II Chronicles, chapter 3 and 4, which account as {36} well as the description given by Josephus[39] appears to have been derived from the record first cited. In general, the design of Solomon's Temple was that of the specially constructed Tabernacle of the Congregation, though the dimensions of the Temple were double those of the Tabernacle. It will be remembered that the porch of the Tabernacle was five cubits deep; that of the Temple measured ten cubits in depth; in each case the porch extended across the full width of the house. The Holy Place, or first compartment within the walls, was twenty cubits long, ten cubits wide and ten high in the Tabernacle; that of the Temple was forty by twenty cubits and twenty cubits high. The inner sanctuary, Oracle, or Holy of Holies, in the Tabernacle was cubical and measured ten cubits each way; in the Temple this sacred enclosure was a cube of twenty cubits. Thus the ground plan of the Tabernacle covered thirty-five by twenty cubits, and that of the Temple seventy cubits by forty. These measurements do not take into account the side chambers, which in the Tabernacle were five cubits wide; those connected with the Temple measured ten cubits in extreme width; with these included, the entire area of the Tabernacle was forty by twenty cubits, and that of the Temple eighty by forty cubits; or, at the usually accepted equivalent for the cubit, sixty by thirty feet for the Tabernacle, and one hundred and twenty feet by sixty feet for the Temple. In height the same relation was maintained; the Tabernacle rose fifteen cubits and the Temple thirty cubits. The Temple porch appears to have towered above the height of the main structure.[40]
