'Threshing floor' in the Bible

And when they came on the threshing floor of Chidon, Uzzah put forth his hand to hold the ark, for the oxen stumbled.

And God sent the angel to Jerusalem to destroy it. And as he was about to destroy, the LORD beheld and had compassion on the wretchedness, and said to the angel that destroyed, "It is enough, now cease thine hand." And the angel of the LORD stood by the threshing floor of Ornan the Jebusite.

And the Angel commanded Gad to say to David, that David should go and rear up an altar unto the LORD, in the threshing floor of Ornan the Jebusite.

And David came to Ornan. And when Ornan looked and saw David, he went out of the threshing floor and bowed himself to David with his face to the ground.

And David said to Ornan, "Give me the place of the threshing floor, that I may build an altar therein unto the LORD. Let me have it for as much money as it is worth, that the plague may cease from the people."

At that time, when David saw that the LORD had heard him in the threshing floor of Ornan the Jebusite, he used to offer there.
