2 Samuel 24:17-19

Amplified Bible

¹⁷ When David saw the angel who was striking down the people, he spoke to the Lord and said, “Behold, I [alone] am the one who has sinned and done wrong; but these sheep (people of Israel), what have they done [to deserve this]? Please let Your hand be [only] against me and my father’s house (family).”

David Builds an Altar

¹⁸ Then Gad [the prophet] came to David that day and said to him, “Go up, set up an altar to the Lord on the threshing floor of Araunah the Jebusite [where you saw the angel].” ¹⁹ So David went up according to Gad’s word, as the Lord commanded.
