'Threshing floor' in the Bible

When they came to the threshing floor of Chidon, Uzza put out his hand to hold the ark, because the oxen nearly upset it.

And God sent an angel to Jerusalem to destroy it; but as he was about to destroy it, the Lord saw and was sorry over the calamity, and said to the destroying angel, “It is enough; now relax your hand.” And the angel of the Lord was standing by the threshing floor of Ornan the Jebusite.

Then the angel of the Lord commanded Gad to say to David, that David should go up and build an altar to the Lord on the threshing floor of Ornan the Jebusite.

As David came to Ornan, Ornan looked and saw David, and went out from the threshing floor and prostrated himself before David with his face to the ground.

Then David said to Ornan, “Give me the site of this threshing floor, that I may build on it an altar to the Lord; for the full price you shall give it to me, that the plague may be restrained from the people.”

At that time, when David saw that the Lord had answered him on the threshing floor of Ornan the Jebusite, he offered sacrifice there.
