'Threshing floor' in the Bible

Then Solomon began to build the house of Yahweh in Jerusalem, on Mount Moriah, where Yahweh had appeared to David his father, at the place that David had established, on the threshing floor of Ornan the Jebusite.

Now the king of Israel and Jehoshaphat the king of Judah were each sitting on his throne, clothed in robes. And they were sitting at the threshing floor at the entrance of the gate of Samaria, and all the prophets were prophesying before them.
