So Gad went to David that day and told him, “Go up and build an altar for the Lord on the threshing floor of Araunah the Jebusite.”

So the Lord’s messenger told Gad to instruct David to go up and build ¹  an altar for the Lord on the threshing floor of Ornan the Jebusite.

Then the king and his men advanced to Jerusalem ¹  against the Jebusites who lived in the land. The Jebusites ²  said to David, “You cannot invade this place! Even the blind and the lame will turn you back, saying, ‘David cannot invade this place!’”

When the angel ¹  extended his hand to destroy Jerusalem, the Lord relented from his judgment. ²  He told the angel who was killing the people, “That’s enough! Stop now!” ³  (Now the Lord’s angel was near the threshing floor of Araunah the Jebusite.)
