1 Chronicles 21:16-19

16When David looked up, he saw the Messenger of the Lord standing between heaven and earth. The Messenger had a sword in his hand and stretched it over Jerusalem. David and the leaders were dressed in sackcloth. They bowed down with their faces touching the ground.

17David said to God, “I’m the one who ordered the people to be counted. I am the one who sinned and did wrong. What have these sheep done? Lord my God, let your punishment be against me and my father’s family, but don’t punish your people with a plague.”

18The Lord’s Messenger told Gad to tell David to go and set up an altar for the Lord at Ornan the Jebusite’s threshing floor.

19David went as Gad had told him in the Lord’s name.
