דברי הימים א, פרק כ״א, פסוק כ״ג

When approached by King David, Ornan responds with extraordinary generosity. He offers to give the king not only the physical location of the threshing floor but also all the necessary materials for the sacrifice, completely free of charge. This detailed account in the Book of Chronicles expands upon the briefer description found in the Book of Samuel [רלב״ג].

Ornan presents the threshing floor as an outright gift [מצודת דוד, ביאור שטיינזלץ]. He invites the king to use his personal property freely to bring offerings to God exactly as he desires [מצודת דוד]. Going above and beyond, Ornan insists on providing everything required so that David will not have to purchase a single item. He offers his own cattle to serve as the burnt offerings and the wheat currently on the threshing floor for the meal offering [ביאור שטיינזלץ].

Furthermore, he offers his threshing sledges to be used as firewood to light the altar [מצודת דוד, ביאור שטיינזלץ]. These sledges were heavy wooden boards, embedded with small stones on the bottom, which were dragged by animals to thresh the grain [רש״י, מצודת ציון, ביאור שטיינזלץ].
