2 Samuel 24:16-18

16But when the Messenger stretched out his arm to destroy Jerusalem, the Lord changed his mind about the disaster. “Enough!” he said to the Messenger who was destroying the people. “Put down your weapon.” The Messenger of the Lord was at the threshing floor  of Araunah the Jebusite.

17When David saw the Messenger who had been killing the people, he said to the Lord, “I’ve sinned. I’ve done wrong. What have these sheep done? Please let your punishment be against me and against my father’s family.”

18That day Gad came to David and said to him, “Go, set up an altar for the Lord at Araunah the Jebusite’s threshing floor.”
