1 Chronicles 21:20-23

20Now Ornan was threshing wheat, and he turned back and saw the angel; and his four sons who were with him hid themselves.

21As 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.

22Then 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.”

23Ornan said to David, “Take it for yourself; and let my lord the king do what is good in his eyes. See, I will give you the oxen also for burnt offerings and the threshing sledges (heavy wooden platforms) for wood and the wheat for the grain offering; I give it all.”
