David’s Altar and Sacrifice

¹⁸ Then the angel of the Lord commanded Gad to tell David that he should go up and erect an altar to the Lord on the threshing-floor of Ornan the Jebusite. 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.
