³ And he hath gone inward, and measureth the post of the opening two cubits, and the opening six cubits, and the breadth of the opening seven cubits.

⁴ And he measureth its length twenty cubits, and the breadth twenty cubits, unto the front of the temple, and he saith unto me, `This [is] the holy of holies.'
