1 Chronicles 21:14-16

So the LORD sent a plague upon Israel, and 70,000 people died as a result. And 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. David 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.
