1 Chronicles 21:15-16

15God sent an angel to Jerusalem to destroy it; and as he was destroying it, the Lord looked, and relented concerning the catastrophe and said to the destroying angel, “It is enough; now remove your hand [of judgment].” And the angel of the Lord was standing by the threshing floor of Ornan the Jebusite.

16Then David raised his eyes and saw the angel of the Lord standing between earth and heaven, having a drawn sword in his hand stretched out over Jerusalem. Then David and the elders, covered in sackcloth, fell on their faces.
