26 David built an altar to Yahweh there, and offered burnt offerings and peace offerings, and called on Yahweh; and he answered him from the sky by fire on the altar of burnt offering.

He answered him from heaven by fire - This fact is not mentioned by the author of Samuel, since his object is to give an account of the sin of David, its punishment, and the circumstances by which that punishment was brought to a close, not to connect those circumstances with anything further in the history. With the writer of Chronicles the case is different. He would probably have omitted the whole narrative, as he did the sin of David in the matter of Uriah, but for its connection with the fixing of the temple site 1 Chr. 22. It was no doubt mainly the fact that God answered him by fire from heaven on this altar, which determined David, and Solomon after him, to build the temple on the spot so consecrated.
He answered him - by fire - In answer to David's prayers, God, to show that he had accepted him, and was now pacified towards him and the people, sent fire from heaven and consumed the offerings.
And David built there an altar unto the LORD, and offered burnt offerings and peace offerings, and called upon the LORD; and he (n) answered him from heaven by fire upon the altar of burnt offering.
(n) God declared that he heard his request, in that he sent down fire from heaven for they could use no fire in sacrifice but that which was reserved still upon the altar, (Leviticus 6:13) and came down from heaven, (Leviticus 9:24) as appeared by the punishment of Nadab and Abihu, (Leviticus 10:1).
David built there an altar--He went in procession with his leading men from the royal palace, down Mount Zion, and through the intervening city. Although he had plenty of space on his own property, he was commanded, under peremptory direction, to go a considerable distance from his home, up Mount Moriah, to erect an altar on premises which he had to buy. It was on or close to the spot where Abraham had offered up Isaac.
answered him by fire from heaven--(See Leviticus 9:24; 1-Kings 18:21-23; 2-Kings 1:12; 2-Chronicles 7:1).
In 2-Samuel 24:25 the conclusion of this event is shortly narrated thus: David offered burnt-offerings and peace-offerings, and Jahve was entreated for the land, and the plague was stayed from Israel. In the Chronicle we have a fuller statement of the יהוה יעתר in 1-Chronicles 21:26. David called upon Jahve, and He answered with fire from heaven upon the altar of burnt-offering (1-Chronicles 21:27); and Jahve spake to the angel, and he returned the sword into its sheath. The returning of the sword into its sheath is a figurative expression for the stopping of the pestilence; and the fire which came down from heaven upon the altar of burnt-offering was the visible sign by which the Lord assured the king that his prayer had been heard, and his offering graciously accepted. The reality of this sign of the gracious acceptance of an offering is placed beyond doubt by the analogous cases, Leviticus 9:24; 1-Kings 18:24, 1-Kings 18:38, and 2-Chronicles 7:1. It was only by this sign of the divine complacence that David learnt that the altar built upon the threshing-floor of Araunah had been chosen by the Lord as the place where Israel should always thereafter offer their burnt-offerings and sacrifices, as is further recorded in 1-Chronicles 21:28-30. and in 1-Chronicles 22:1. From the cessation of the pestilence in consequence of his prayer and sacrifice, David could only draw the conclusion that God had forgiven him his transgression, but could not have known that God had chosen the place where he had built the altar for the offering demanded by God as a permanent place of sacrifice. This certainly he obtained only by the divine answer, and this answer was the fire which came down upon the altar of burnt-offering and devoured the sacrifice. This 1-Chronicles 21:28 states: "At the time when he saw that Jahve had answered him at the threshing-floor of Ornan, he offered sacrifice there," i.e., from that time forward; so that we may with Berth. translate שׁם ויּזבּח, "then he was wont to offer sacrifice there." In 1-Chronicles 21:29 and 1-Chronicles 21:30 we have still further reasons given for David's continuing to offer sacrifices at the threshing-floor of Ornan. The legally sanctioned place of sacrifice for Israel was still at that time the tabernacle, the Mosaic sanctuary with its altar of burnt-offering, which then stood on the high place at Gibeon (cf. 1-Chronicles 16:39). Now David had indeed brought the ark of the covenant, which had been separated from the tabernacle from the time of Samuel, to Zion, and had there not only erected a tent for it, but had also built an altar and established a settled worship there (1 Chron 17), yet without having received any express command of God regarding it; so that this place of worship was merely provisional, intended to continue only until the Lord Himself should make known His will in the matter in some definite way. When therefore David, after the conquest of his enemies, had obtained rest round about, he had formed the resolution to make an end of this provisional separation of the ark from the tabernacle, and the existence of two sacrificial altars, by building a temple; but the Lord had declared to him by the prophet Nathan, that not he, but his son and successor on the throne, should build Him a temple. The altar by the ark in Zion, therefore, continued to co-exist along with the altar of burnt-offering at the tabernacle in Gibeon, without being sanctioned by God as the place of sacrifice for the congregation of Israel. Then when David, by ordering the numbering of the people, had brought guilt upon the nation, which the Lord so heavily avenged upon them by the pestilence, he should properly, as king, have offered a sin-offering and a burnt-offering in the national sanctuary at Gibeon, and there have sought the divine favour for himself and for the whole people. But the Lord said unto him by the prophet Gad, that he should bring his offering neither in Gibeon, nor before the ark on Zion, but in the threshing-floor of Ornan (Araunah), on the altar which he was there to erect. This command, however, did not settle the place where he was afterwards to sacrifice. But David - so it runs, 1-Chronicles 21:29. - sacrificed thenceforward in the threshing-floor of Ornan, not at Gibeon in the still existent national sanctuary, because he (according to 1-Chronicles 21:30) "could not go before it (לפניו) to seek God, for he was terrified before the sword of the angel of Jahve." This statement does not, however, mean, ex terrore visionis angelicae infirmitatem corporis contraxerat (J. H. Mich.), nor yet, "because he, being struck and overwhelmed by the appearance of the angel, did not venture to offer sacrifices elsewhere" (Berth.), nor, "because the journey to Gibeon was too long for him" (O. v. Gerl.). None of these interpretations suit either the words or the context. חרב מפּני נבעת, terrified before the sword, does indeed signify that the sword of the angel, or the angel with the sword, hindered him from going to Gibeon, but not during the pestilence, when the angel stood between heaven and earth by the threshing-floor of Araunah with the drawn sword, but - according to the context - afterwards, when the angelophany had ceased, as it doubtless did simultaneously with the pestilence. The words וגו נבעת כּי can therefore have no other meaning, than that David's terror before the sword of the angel caused him to determine to sacrifice thereafter, not at Gibeon, but at the threshing-floor of Araunah; or that, since during the pestilence the angel's sword had prevented him from going to Gibeon, he did not venture ever afterwards to go. But the fear before the sword of the angel is in substance the terror of the pestilence; and the pestilence had hindered him from sacrificing at Gibeon, because Gibeon, notwithstanding the presence of the sanctuary there, with the Mosaic altar, had not been spared by the pestilence. David considered this circumstance as normative ever for the future, and he always afterwards offered his sacrifices in the place pointed out to him, and said, as we further read in 1-Chronicles 22:1, "Here (הוּא זה, properly this, mas. or neut.) is the house of Jahve God, and here is the altar for the burnt-offering of Israel." He calls the site of the altar in the threshing-floor of Araunah יהוה בּית, because there Jahve had manifested to him His gracious presence; cf. Genesis 28:17.
By fire - Hebrews. by fire sent from heaven: which was the sign of God's acceptance. The fire that might justly have fastened on the sinner, fastened upon the sacrifice and consumed it. Thus Christ was made sin and a curse for us, and it pleased the Lord to bruise him, that through him God might be to us, not a consuming fire, but a reconciled Father.
