18 And that day Gad came to David and said to him, Go up, and put up an altar to the Lord on the grain-floor of Araunah the Jebusite. 19 So David went up, as Gad had said and as the Lord had given orders. 20 And Araunah, looking out, saw the king and his servants coming to him: and Araunah went out, and went down on his face to the earth before the king. 21 And Araunah said, Why has my lord the king come to his servant? And David said, To give you a price for your grain-floor, so that I may put up an altar to the Lord, and the disease may be stopped among the people. 22 And Araunah said to David, Let my lord the king take whatever seems right to him, and make an offering of it: see, here are the oxen for the burned offering, and the grain-cleaning instruments and the ox-yokes for wood: 23 All this does the servant of my lord the king give to the king. And Araunah said, May the Lord your God be pleased with your offering! 24 And the king said to Araunah, No, but I will give you a price for it; I will not give to the Lord my God burned offerings for which I have given nothing. So David got the grain-floor and the oxen for fifty shekels of silver.

Commentary on 2 Samuel 24:18-25
(Read 2 Samuel 24:18-25)
God's encouraging us to offer to him spiritual sacrifices, is an evidence of his reconciling us to himself. David purchased the ground to build the altar. God hates robbery for burnt-offering. Those know not what religion is, who chiefly care to make it cheap and easy to themselves, and who are best pleased with that which costs them least pains or money. For what have we our substance, but to honour God with it; and how can it be better bestowed? See the building of the altar, and the offering proper sacrifices upon it. Burnt-offerings to the glory of God's justice; peace-offerings to the glory of his mercy. Christ is our Altar, our Sacrifice; in him alone we may expect to escape his wrath, and to find favour with God. Death is destroying all around, in so many forms, and so suddenly, that it is madness not to expect and prepare for the close of life.
