'Platform' in the Bible

(For Solomon had made a platform of bronze five cubits long and five cubits wide and three cubits high, and placed it in the midst of the outer court.) And he stood upon it, then knelt down on his knees before the whole assembly of Israel and spread out his hands to heaven.

Then Jeshua, Bani, Kadmiel, Shebaniah, Bunni, Sherebiah, Bani, and Kenani stood on the platform of the Levites and cried out with a loud voice to Yahweh their God.

And I saw for the temple a platform {all the way around} the foundations of the side rooms; [it was] the length of a full reed, six cubits long.
