And Gad came that day to David, and said unto him, Go up, rear an altar unto the LORD in the threshingfloor of Araunah the Jebusite.

And Gad came that day to David, and said unto him, Go up, rear an altar unto Jehovah in the threshing-floor of Araunah the Jebusite.

And Gad came to David that day, and said: Go up, and build an altar to the Lord in the thrashingfloor of Areuna the Jebusite.

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;'

And Gad came that day to David, and said to him, Go up, raise an altar to the LORD in the threshing floor of Araunah the Jebusite.

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.

Then Gad went to David on that day, and he said, "Ascend and construct an altar to the Lord on the threshing floor of Araunah the Jebusite."

Go up, rear an altar unto the Lord - This place is supposed to be Mount Moriah: on which, according to the rabbins, Cain and Abel offered their sacrifices; where Abraham attempted to sacrifice Isaac, and where the temple of Solomon was afterwards built.

And Gad came that day to David,.... Ordered and directed by the angel of the Lord, 1-Chronicles 21:18,
and said unto him, go up, rear an altar unto the Lord in the threshing floor of Araunah the Jebusite: it was too far to go to Gibeon, where the tabernacle was, at such a time of extremity, when the sword of the angel was stretched out over Jerusalem, 1-Chronicles 21:29; and this was the most proper place, as it was the very spot over and nearest to which the angel was; and was on Mount Moriah, where the Jews say Abraham offered up Isaac; and where the temple was afterwards built, as Kimchi and Ben Gersom observe; and Eupolemus, an Heathen writer (g), says, that when David desired to build a temple for God, and that he would show him the place of the altar, an angel appeared to him, standing over the place where the altar at Jerusalem was to be built.
(g) Apud Euseb. Evangel. Praepar. l. 9. c. 30. p. 447.

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.

Araunah--or Ornan (1-Chronicles 21:18), the Jebusite, one of the ancient inhabitants, who, having become a convert to the true religion, retained his house and possessions. He resided on Mount Moriah, the spot on which the temple was afterwards built (2-Chronicles 3:1); but that mount was not then enclosed in the town.

David's prayer was heard. The prophet Gad came and said to him by command of Jehovah, "Go up, and erect an altar to the Lord upon the floor of Aravnah the Jebusite." This is all that is communicated here of the word of Jehovah which Gad was to convey to the king; the rest is given afterwards, as is frequently the case, in the course of the subsequent account of the fulfilment of the divine command (2-Samuel 24:21). David was to build the altar and offer burnt-offerings and supplicatory-offerings upon it, to appease the wrath of Jehovah. The plague would then be averted from Israel.
