1 Chronicles 21:20-22

New International Version

²⁰ While Araunah was threshing wheat,^(A) he turned and saw the angel; his four sons who were with him hid themselves. ²¹ Then David approached, and when Araunah looked and saw him, he left the threshing floor and bowed down before David with his face to the ground.

²² David said to him, “Let me have the site of your threshing floor so I can build an altar to the Lord, that the plague on the people may be stopped. Sell it to me at the full price.”
