Now the king of Israel and Jehoshaphat the king of Judah were sitting, each on his throne and dressed in royal 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. Bible see other translations

“threshing-floor at the entrance.” This threshing-floor would be outside the gate and since it was flat would be a convenient place to set up the kings’ thrones. The threshing-floor would not be in the city. The king’s “sat” while the prophet’s prophesied,, and the Bible the word “sat” often indicates taking a ruling position.
