2 Samuel 24:20
And Araunah looked, and saw the king and his servants coming on toward him: and Araunah went out, and bowed himself before the king on his face upon the ground. And Araunah looked, and saw the king and his servants coming on toward him: and Araunah went out, and bowed himself before the king on his face upon the ground.
Araunah looked up and saw the king with his servants coming toward him, went out to meet them, and bowed himself before the king with his face to the ground. In that meeting he freely offered David his threshing-floor as a place to build an altar to the Lord, together with cattle and everything needful for the sacrifice. That altar and sacrifice were to make atonement for David's sin in numbering Israel and to stop the pestilence, which was the atonement God commanded through His prophet. David refused to take it as a gift, declaring that the Lord would accept the sacrifice he was willing to make but that he would not come before the Lord with an offering that cost him nothing, so he bought it for the full price.
There he offered burnt-offerings and peace-offerings with his heart in the work, and his repentance was accepted. God showed His acceptance by answering with fire from heaven to consume the sacrifice. The angel was then commanded to put his sword back into its sheath and to cease destroying Jerusalem.
