1 Kings 6:3

the porch This extended along the whole face of the building, and projected forward 10 cubits, thus making the whole length of the structure 70 cubits or 105 feet, without allowing for the thickness of outside or party walls. The height of this porch is said (2 Chronicles 3:4) to have been 120 cubits. This height = 180 ft. is out of proportion to the other dimensions, and Mr Robins suggests that, after his manner, the Chronicler has added together the 4 dimensions in height of the 4 sides of the porch, and that the true height was 30 cubits. That the Chronicler does put down his numbers in this strange fashion is shewn from 2 Chronicles 3:11, where he first writes -the wings of the cherubim were twenty cubits long." He afterwards explains that he means each of the 4 wings was 5 cubits long, but left alone the first statement would be misleading. In the same manner the pillars which in 1 Kings 7:15; Jeremiah 52:17 are said to be each 18 cubits high, are described in 2 Chronicles 3:15 as -two pillars of thirty and five cubits high". Where it is suggested that the two heights given in Kings are added together.

the temple of the house This means the holy place. Cf. below 1 Kings 6:17, where it is called -the temple before the oracle." The -oracle" is the special name for the most holy place.
