as well as the Jebusites, Amorites, Girgashites,

David and the whole Israelite army ¹  advanced to Jerusalem (that is, Jebus). ²  (The Jebusites, the land’s original inhabitants, lived there.) ³ 

At that time, when David saw that the Lord responded to him at the threshing floor of Ornan the Jebusite, he sacrificed there.

¹  David said, “Whoever attacks ²  the Jebusites first will become commanding general!” ³  So Joab son of Zeruiah attacked ⁴  first and became commander. ⁵ 

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.

God sent an angel ¹  to ravage ²  Jerusalem. As he was doing so, ³  the Lord watched ⁴  and relented from ⁵  his judgment. ⁶  He told the angel who was destroying, “That’s enough! ⁷  Stop now!” ⁸  Now the Lord’s angel was standing near the threshing floor of Ornan ⁹  the Jebusite.
