Now these are the foundations which Solomon laid for building the house of God. The length in cubits, according to the old standard, was sixty cubits, and the width, twenty cubits.

The porch which was in front of the house was as long as the width of the house, twenty cubits, and the height twenty; and inside he overlaid it with pure gold.

He overlaid the main room with juniper wood and overlaid it with fine gold; and he ornamented it with palm trees and chains.
