'Threshing floor' in the Bible

And when they came unto the threshingfloor of Chidon, Uzza put forth his hand to hold the ark; for the oxen stumbled.

And God sent an angel unto Jerusalem to destroy it: and as he was destroying, the LORD beheld, and he repented him of the evil, and said to the angel that destroyed, It is enough, stay now thine hand. And the angel of the LORD stood by the threshingfloor of Ornan the Jebusite.

So the angel of the ORD remained standing near the threshing floor that belonged to Ornan the Jebusite. David looked up and saw the angel of the LORD standing between earth and heaven, with a drawn sword in his hand stretched out over Jerusalem. Then David and the elders, clothed in sackcloth, fell on their faces.

Then the angel of the LORD commanded Gad to say to David, that David should go up, and set up an altar unto the LORD in the threshingfloor of Ornan the Jebusite.

And as David came to Ornan, Ornan looked and saw David, and went out of the threshingfloor, and bowed himself to David with his face to the ground.

Then David said to Ornan, Grant me the place of this threshingfloor, that I may build an altar therein unto the LORD: thou shalt grant it me for the full price: that the plague may be stayed from the people.

At that time when David saw that the LORD had answered him in the threshingfloor of Ornan the Jebusite, then he sacrificed there.
