2 Chronicles 3:1-3

1And Solomon began to build the house of Jehovah at Jerusalem on mount Moriah, where he appeared to David his father, in the place that David had prepared in the threshing-floor of Ornan the Jebusite.

2And he began to build on the second of the second month, in the fourth year of his reign.

3And this was Solomon's foundation for the construction of the house of 1God. The length by cubits after the first measure was sixty cubits, and the breadth twenty cubits.
