'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.
