Jerome, on 1Chr 21:18

“And the angel of the Lord commanded Gad to tell David, to go up, and build an altar to the Lord God in the thrashingfloor of Ornan the Jebusite.”

“When of old the Philistines had been overcome, when their devilish audacity had been destroyed, when their champion had fallen on his face to the earth, it was from this city that there went forth a procession of jubilant souls, a harmonious choir to sing our David's victory over tens of thousands. Here, too, it was that the angel grasped his sword, and while he laid waste the whole of the ungodly city, he marked out the temple of the Lord in the threshing floor of Ornan, king of the Jebusites. Thus early was it made plain that Christ's church would grow up not in Israel but among the Gentiles.”
