Melachim Alef 6:1-2

Orthodox Jewish Bible

6 And it came to pass in the four hundred and eightieth year after the Bnei Yisroel were come out of Eretz Mitzrayim , in the fourth year of Sh’lomo’s reign over Yisroel, in the month Ziv, which is the second month, that he began to build the Beis Hashem.

² And the Beis [Hamikdash] which king Sh’lomo built for Hashem, the length thereof was threescore cubits, and the breadth thereof twenty cubits, and the height thereof thirty cubits.
