2 Samuel 24:16-18

16Then the angel extended his hand toward Jerusalem to destroy it, but the Lord relented concerning the destruction and said to the angel who was destroying the people, “Enough, withdraw your hand now!” The angel of the Lord was then at the threshing floor of Araunah the Jebusite.

17When David saw the angel striking the people, he said to the Lord, “Look, I am the one who has sinned; I am the one who has done wrong. But these sheep, what have they done? Please, let your hand be against me and my father’s family.”

18Gad came to David that day and said to him, “Go up and set up an altar to the Lord on the threshing floor of Araunah the Jebusite.”
