David built his altar, and offered up his sacrifices and prayers to Jehovah. Then, in answer to David’s prayers, as later in answer to Solomon’s, fire fell from heaven upon the altar of burnt offering, and all this while the sword of Jehovah flamed across the heavens above Jerusalem, and the destroying angel remained passive, but to all appearances unappeased. But as the fire of God fell from heaven, Jehovah gave yet another final and convincing token that He would no longer execute judgment against His people. In spite of all that had happened to reassure them, the spectators must have been thrilled with alarm when they saw that the angel of Jehovah no longer remained stationary, and that his flaming sword was moving through the heavens. Their renewed terror was only for a moment: “the angel put up his sword again into the sheath thereof,” and the people breathed more freely when they saw the instrument of Jehovah’s wrath vanish out of their sight. The use of Machpelah as a patriarchal burying-place led to the establishment of a sanctuary at Hebron, which continued to be the seat of a debased and degenerate worship even after the coming of Christ. It is even now a Mohammedan holy place. But on the threshing-floor of Ornan the Jebusite there was to arise a more worthy memorial of the mercy and judgment of Jehovah. Without the aid of priestly oracle or prophetic utterance, David was led by the Spirit of the Lord to discern the significance of the command to perform an irregular sacrifice in a hitherto unconsecrated place. When the sword of the destroying angel interposed between David and the Mosaic tabernacle and altar of Gibeon, the way was not merely barred against the king and his court on one exceptional occasion. The incidents of this crisis symbolised the cutting off for ever of the worship of Israel from its ancient shrine and the transference of the Divinely appointed centre of the worship of Jehovah to the threshing-floor of Ornan the Jebusite, that is to say to Jerusalem, the city of David and the capital of Judah. The lessons of this incident, so far as the chronicler has simply borrowed from his authority, belong to the exposition of the book of Samuel. The main features peculiar to Chronicles are the introduction of the evil angel Satan, together with the greater prominence given to the angel of Jehovah, and the express statement that the scene of David’s sacrifice became the site of Solomon’s altar of burnt offering.
