1 Kings 6:2

The house; properly so called, as distinct from all the walls and buildings which were adjoining to it, to wit, the holy and most holy place. The length thereof; from east and to west. And this and the other measures may seem to belong to the inside from wall to wall. Threescore cubits; cubits of the sanctuary; of which See Poole on "Genesis 6:15". The height thereof, to wit, of the house; for the porch was 120 cubits high, 2 Chronicles 3:4. So that all the measures compared each with other were harmonious. For 60 to 20 (the length to the breadth) is triple, or as 3 to 1; and 60 to 30 (the length to the height) is double, or as 2 to 1; and 30 to 20 (the height to the breadth) is sesquialter, or one and a half, as 3 to 2; which are the proportions answering to the three great concords in music, commonly called a twelfth, an eighth, and a fifth; which therefore must needs be a graceful proportion to the eye, as that in music is graceful to the ear.
