“Then King Solomon stood before the altar of Yahweh in the presence of the whole assembly of Israel. He spread his hands. King Solomon had made a bronze platform five cubits long, five cubits wide, and three cubits high. He had set it in the court. He stood upon it. Then he knelt on his knees in the presence of the whole assembly of Israel. He spread out his hands toward heaven.”
This time there is an elaboration on 1 Kings, chapter 8. The first sentence is the same, but then there was an introduction of a 5 cubit square bronze platform, 3 cubits high (about 4-5 feet high) that he stood on. Then he knelt on this new bronze square plate with his hands towards heaven.
