18 And Gad cometh in unto David on that day, and saith to him, 'Go up, raise to Jehovah an altar in the threshing-floor of Araunah the Jebusite;' 19 and David goeth up, according to the word of Gad, as Jehovah commanded. 20 And Araunah looketh, and seeth the king and his servants passing over unto him, and Araunah goeth out and boweth himself to the king—his face to the earth. 21 And Araunah saith, 'Wherefore hath my lord the king come unto his servant?' and David saith, 'To buy from thee the threshing-floor, to build an altar to Jehovah, and the plague is restrained from the people.' 22 And Araunah saith unto David, 'Let my lord the king take and cause to ascend that which is good in his eyes; see, the oxen for a burnt-offering, and the threshing instruments, and the instruments of the oxen, for wood;' 23 the whole hath Araunah given, 'as' a king to a king; and Araunah saith unto the king, 'Jehovah thy God doth accept thee.' 24 And the king saith unto Araunah, 'Nay, for I do surely buy from thee for a price, and I do not cause to ascend to Jehovah my God burnt-offerings for nought;' and David buyeth the threshing-floor and the oxen for fifty shekels of silver,

(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.
