1 Chronicles 21:20-21

And Ornan turned back, and saw the angel; and his four sons with him hid themselves. Now Ornan was threshing wheat. {And Ornan...: or, When Ornan turned back and saw the angel, then he and his four sons with him hid themselves} And as David came to Ornan, Ornan looked and saw David, and went out of the threshingfloor, and bowed himself to David with {his} face to the ground.
