16 And David lifted up his eyes, and saw the angel of the LORD stand between the earth and the heaven, having a drawn sword in his hand stretched out ever Jerusalem. Then David and the elders, clothed in sackcloth, fell upon their faces.
17 And David said unto God, Is it not I that commanded the people to be numbered? even I it is that have sinned and done very wickedly; but these sheep, what have they done? let thine hand, I pray thee, O LORD my God, be against me, and against my father's house; but not against thy people, that they should be plagued.
18 Then the angel of the LORD commanded Gad to say to David, that David should go up, and rear an altar unto the LORD in the threshing-floor of Ornan the Jebusite.
19 And David went up at the saying of Gad, which he spake in the name of the LORD.
20 And Ornan turned back, and saw the angel; and his four sons that were with him hid themselves. Now Ornan was threshing wheat.
21 And as David came to Ornan, Ornan looked and saw David, and went out of the threshing-floor, and bowed himself to David with his face to the ground.
22 Then David said to Ornan, Give me the place of this threshing-floor, that I may build thereon an altar unto the LORD: for the full price shalt thou give it me: that the plague may be stayed from the people.
