1 Chronicles 21:15-18

15And God sent an angel to destroy Jerusalem. But just as the angel was preparing to destroy it, the Lord relented and said to the death angel, “Stop! That is enough!” At that moment the angel of the Lord was standing by the threshing floor of Araunah the Jebusite.

16David looked up and saw the angel of the Lord standing between heaven and earth with his sword drawn, reaching out over Jerusalem. So David and the leaders of Israel put on burlap to show their deep distress and fell face down on the ground.

17And David said to God, “I am the one who called for the census! I am the one who has sinned and done wrong! But these people are as innocent as sheep—what have they done? O Lord my God, let your anger fall against me and my family, but do not destroy your people.”

18Then the angel of the Lord told Gad to instruct David to go up and build an altar to the Lord on the threshing floor of Araunah the Jebusite.
