'Threshing floor' in the Bible

And when they came to the threshing floor of Kidon, Uzza reached out his hand to hold the ark because the cattle had stumbled.

And God sent an angel to Jerusalem to destroy it, and as [he was about] to destroy [it], Yahweh saw and was grieved on account of the calamity. Then he said to the angel, the destroyer, "[It is] enough; slacken your hand." And the angel of Yahweh was standing by the threshing floor of Ornan the Jebusite.

Then David came to Ornan, and Ornan looked and saw David. And he went out from the threshing floor, and they bowed down to David, faces to the ground.

Then David said to Ornan, "Please give me the place, the threshing floor, that I might build an altar on it to Yahweh; at full price please give it to me, that the plague against the people might be stopped."

At that time, when David saw that Yahweh answered him at the threshing floor of Ornan the Jebusite, he sacrificed there.
