1 Chronicles 21:19-21

New Revised Standard Version Catholic Edition

¹⁹ So David went up following Gad’s instructions, which he had spoken in the name of the Lord. ²⁰ Ornan turned and saw the angel; and while his four sons who were with him hid themselves, Ornan continued to thresh wheat. ²¹ As David came to Ornan, Ornan looked and saw David; he went out from the threshing floor, and did obeisance to David with his face to the ground.
