'Price' in the Bible

Then David said to Ornan, "Give me the place of this threshing floor, that I may build thereon an altar to Yahweh. You shall sell it to me for the full price, that the plague may be stopped from afflicting the people."

King David said to Ornan, "No; but I will most certainly buy it for the full price. For I will not take that which is yours for Yahweh, nor offer a burnt offering without cost."
