'Platform' in the Bible

When she looked, behold, there stood the [young] king [on the platform] by the pillar, as was customary [on such occasions], and the captains and the trumpeters were beside the king; and all the people of the land rejoicing and blowing the trumpets. Then Athaliah tore her clothes and cried, “Treason! Treason!”

The king stood by the pillar and made a covenant before the Lord, to walk after the Lord and to keep His commandments, His testimonies, and His statutes with all his heart and soul, to confirm the words of this covenant that were written in this book. And all the people entered into the covenant.

I also saw that the temple (house) had a raised platform all around it; the foundations of the side chambers measured a full rod of six long cubits in height.

and the outer chambers was a width of twenty cubits all around the temple on every side.

The doorways of the side chambers toward the free space were one doorway toward the north and another doorway toward the south; and the width of the free space was five cubits all around.
