And the house which king Solomon built for the LORD, the length thereof was threescore cubits, and the breadth thereof twenty cubits, and the height thereof thirty cubits.

Wesley's Notes

6:2 The house - Properly so called, as distinct from all the walls and buildings which were adjoining to it; namely, the holy, and most holy place. Length - From east, to west. And this and the other measures may seem to belong to the inside from wall to wall. Cubits - Cubits of the sanctuary. Height - Namely, of the house: for the porch was one hundred and twenty cubits high, 2Chron 3:4. So that all the measures compared each with other were harmonious. For sixty to twenty (the length to the breadth) is triple: or as three to one: and sixty to thirty (the length to the height) is double, or as two to one: and thirty to twenty (the height to the breadth) is one and an half, as three to two. 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.

Jamieson-Fausset-Brown Bible Commentary

2. 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 (2Ch 3:3), or holy cubit (Eze 40:5; 43:13), a handbreadth longer than the common or later one. It is probable that the internal elevation only is here stated.

Matthew Henry's Concise Commentary

6:1-10 The temple is called the house of the Lord, because it was directed and modelled by him, and was to be employed in his service. This gave it the beauty of holiness, that it was the house of the Lord, which was far beyond all other beauties. It was to be the temple of the God of peace, therefore no iron tool must be heard; quietness and silence suit and help religious exercises. God's work should be done with much care and little noise. Clamour and violence often hinder, but never further the work of God. Thus the kingdom of God in the heart of man grows up in silence, Mr 5:27.
