LXX2012(i)
20 And Orna looked out, and saw the king and his servants coming on before him: and Orna went forth, and did obeisance to the king with his face to the earth.
21 And Orna said, Why has my lord the king come to his servant? and David said, To buy of you the threshing floor, in order to build an altar to the Lord that the plague may be restrained from off the people.
22 And Orna said to David, Let my lord the king take and offer to the Lord that which is good in his eyes: behold, [here are] oxen for a whole burnt offering, and the wheels and furniture of the oxen for wood.
23 Orna gave all to the king: and Orna said to the king, The Lord your God bless you.
24 And the king said to Orna, Nay, but I will surely buy it of you at a fair price, and I will not offer to the Lord my God a whole burnt offering for nothing. So David purchased the threshing floor and the oxen for fifty shekels of silver.
