The foundation Solomon laid for building the temple of God was sixty cubits long and twenty cubits wide (using the cubit of the old standard). (NIV)
Now these are the measurements for the foundations which Solomon laid for the house of God. The length in cubits by the former measure was sixty cubits, and the breadth twenty cubits. (AMP)
Now these are the things wherein Solomon was instructed for the building of the house of God. The length by cubits after the first measure was threescore cubits, and the breadth twenty cubits. (KJV)
