1 Chronicles 21:15-18

15And God sent an angel unto Jerusalem to destroy it: and as he was about to destroy, Jehovah beheld, and he repented him of the evil, and said to the destroying angel, It is enough; now stay thy hand. And the angel of Jehovah was standing by the threshing-floor of Ornan the Jebusite. 16And David lifted up his eyes, and saw the angel of Jehovah standing between earth and heaven, having a drawn sword in his hand stretched out over Jerusalem. Then David and the elders, clothed in sackcloth, fell upon their faces. 17And David said unto God, Is it not I that commanded the people to be numbered? even I it is that have sinned and done very wickedly; but these sheep, what have they done? let thy hand, I pray thee, O Jehovah my God, be against me, and against my father’s house; but not against thy people, that they should be plagued.

18Then the angel of Jehovah commanded Gad to say to David, that David should go up, and rear an altar unto Jehovah in the threshing-floor of Ornan the Jebusite.
