2 Samuel 24:16-18

New Revised Standard Version, Anglicised Catholic Edition

¹⁶ But when the angel stretched out his hand towards Jerusalem to destroy it, the Lord relented concerning the evil, and said to the angel who was bringing destruction among the people, ‘It is enough; now stay your hand.’ The angel of the Lord was then by the threshing-floor of Araunah the Jebusite. ¹⁷ When David saw the angel who was destroying the people, he said to the Lord, ‘I alone have sinned, and I alone have done wickedly; but these sheep, what have they done? Let your hand, I pray, be against me and against my father’s house.’
