1 Chronicles 21:20-22 Amplified Bible (AMP)

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. ²² Then David said to Ornan, “Give me the site of this threshing floor, so that I may build an altar on it to the Lord. You shall charge me the full price for it, so that the plague may be averted from the people.”
