2 Samuel 24:16-18

Revised Standard Version

¹⁶ And when the angel stretched forth his hand toward Jerusalem to destroy it, the Lord repented of the evil, and said to the angel who was working destruction among the people, “It is enough; now stay your hand.” And the angel of the Lord was by the threshing floor of Arau′nah the Jeb′usite. ¹⁷ Then David spoke to the Lord when he saw the angel who was smiting the people, and said, “Lo, I have sinned, and I have done wickedly; but these sheep, what have they done? Let thy hand, I pray thee, be against me and against my father’s house.”

David’s Altar on the Threshing Floor
