2 Samuel 24:16-18

New Catholic Bible

¹⁶ However, when the angel stretched forth his hand toward Jerusalem to destroy it, the Lord regretted the terrible calamity that he had approved, and he said to the angel who was afflicting the people: “That is enough! Stay your hand!” The angel of the Lord was then standing at the threshing floor of Araunah the Jebusite. ¹⁷ When David saw the angel who was striking down the people, he said to the Lord: “I was the one who sinned. I was the one who acted wickedly. What have these sheep done? Let your hand fall upon me and my family.”

¹⁸ Sacrifice of Atonement. On that day Gad came to David and said to him: “Go up and erect an altar to the Lord on the threshing floor of Araunah the Jebusite.”
