Charles Ellicott Commentary 1 Kings 6:3

"And the porch before the temple of the house, twenty cubits was the length thereof, according to the breadth of the house; [and] ten cubits was the breadth thereof before the house." — 1 Kings 6:3 (ASV)

The porch was thirty feet wide and fifteen feet deep. The height is not here given; but in the present text of 2 Chronicles 3:4 (followed by some manuscripts of the Septuagint, and by Josephus) it is made 120 cubits, or 180 feet. This height is hardly in accordance with anything else known on ancient architecture. It is, however, not at all unlike the western tower of a Gothic church.
