2 Samuel 24:16-24

16But when the angel stretched out his hand to destroy Jerusalem, the LORD relented from the calamity and said to the angel who was destroying the people, “Enough! Withdraw your hand now!” At that time the angel of the LORD was by the threshing floor of Araunah1 the Jebusite.

17When David saw the angel striking down the people, he said to the LORD, “Surely I, the shepherd,2 have sinned and acted wickedly. But these sheep, what have they done? Please, let Your hand fall upon me and my father’s house.”

18And that day Gad came to David and said to him, “Go up and build an altar to the LORD on the threshing floor of Araunah the Jebusite.” 19So David went up at the word of Gad, just as the LORD had commanded.

20When Araunah looked out and saw the king and his servants coming toward him, he went out and bowed facedown before the king. 21“Why has my lord the king come to his servant?” Araunah said.

“To buy your threshing floor,” David replied, “that I may build an altar to the LORD, so that the plague upon the people may be halted.”

22Araunah said to David, “May my lord the king take whatever seems good to him and offer it up. Here are the oxen for a burnt offering and the threshing sledges and ox yokes for the wood. 23O king, Araunah gives all these to the king.” He also said to the king, “May the LORD your God accept you.”

24“No,” replied the king, “I insist on paying a price, for I will not offer to the LORD my God burnt offerings that cost me nothing.”

So David bought the threshing floor and the oxen for fifty shekels of silver.3
