Thematic Bible: Of the angel of the lord beside the threshing-floor of ornan

And God sent the angel to Jerusalem to destroy it. And as he was about to destroy, the LORD beheld and had compassion on the wretchedness, and said to the angel that destroyed, "It is enough, now cease thine hand." And the angel of the LORD stood by the threshing floor of Ornan the Jebusite. And David lifted up his eyes and saw the angel of the LORD stand between the earth and heaven with a drawn sword in his hand stretched out toward Jerusalem. Then fell David and the elders of Israel, clothed in sack, upon their faces. And David said unto God, "Is it not I that commanded to number the people? And I am he that have sinned and done evil in deed. But what have these sheep done? Let thine hand therefore O LORD God be on me and on my father's house, and not on thy people to destroy them." read more.
