“In the first year of Cyrus the king the same Cyrus the king made a decree concerning the house of God at Jerusalem, Let the house be builded, the place where they offered sacrifices, and let the foundations thereof be strongly laid; the height thereof threescore cubits, and the breadth thereof threescore cubits;”
King James Version (KJV)
6:3 Cubits - Those proportions differ from those of Solomon's temple, which was but thirty cubits high, only the porch was a hundred and twenty cubits high, and but twenty cubits in breadth. Either therefore Solomon's cubits were sacred cubits, which were larger than the other, and these but common cubits. Or, the sixty cubits of height are meant only for the porch. And the word rendered breadth, may be rendered the extension or the length of it; it being improbable that the king should give orders about the breadth, and none about the length of it.
