1 Chronicles 21:19-21

Amplified Bible

¹⁹ So David went up at Gad’s word, which he spoke in the name of the Lord. ²⁰ Now Ornan was threshing wheat, and he turned back and saw the angel; and his four sons who were with him hid themselves. ²¹ As David came to Ornan, Ornan looked and saw him, and went out from the threshing floor and bowed down before David with his face to the ground.
