'Threshing floor' in the Bible

Solomon began building the Lord's temple in Jerusalem on Mount Moriah, where the Lord had appeared to his father David. This was the place that David prepared at the threshing floor of Ornan the Jebusite.

Now the king of Israel and King Jehoshaphat of Judah were sitting on their respective thrones, dressed in their royal robes, at the threshing floor at the entrance of the gate of Samaria. All the prophets were prophesying before them.
