Divrey Hayamim Bais 3:1-3

Orthodox Jewish Bible

3 Then Sh’lomo began to build the Bais Hashem at Yerushalayim in Mt Moriyah, where Hashem appeared unto Dovid Avihu, in the makom (place) which Dovid had prepared in the goren (threshing floor) of Ornan the Yevusi.

² And he began to build in the second day of the second month, in the fourth year of his [Sh’lomo’s 970-930 B.C.E.] reign.

³ Now these are the foundations which Sh’lomo laid for the building of the Bais HaElohim. The length by cubits using the middah harishonah (old standard) was threescore cubits, and the width twenty cubits.
