25 David built an altar to Yahweh there, and offered burnt offerings and peace offerings. So Yahweh was entreated for the land, and the plague was stayed from Israel.

David - offered burnt-offerings - And that these sacrifices were pleasing to the Lord, is evident from a circumstance marked in the parallel place, 1-Chronicles 21:26 : David called upon the Lord, and he answered him from heaven by fire upon the altar of burnt-offering.
The plague was stalled - Jerusalem did not share in the common calamity, seventy thousand being the whole that were slain throughout the land.
This book is unfinished, and requires 1-Chronicles 22, 23, 24, 25, 26, 27, 28, and 29, to complete it. A few things relative to this history may be found in the beginning of the following book; but the information in 1-Chronicles is much more extensive and satisfactory.
And David built there an altar unto the Lord,.... After he had made the purchase:
and offered burnt offerings and peace offerings; the one to expiate the sin or sins committed, the other to give thanks for the intimation given, that the plague would be stayed upon this:
so the Lord was entreated for the land; was pacified and prevailed upon to remove the pestilence from it; which was signified by fire descending upon the altar of burnt offering, which showed the sacrifice was accepted, and by the angel being ordered to put his sword into its sheath, 1-Chronicles 21:26; and the Targum is,"and the Lord received the prayer of the inhabitants of the land:"
and the plague was stayed from Israel; no more died of the pestilence, either at Jerusalem, or in any other part of the land Israel.
David offered burnt offerings and peace offerings--There seem to have been two sacrifices; the first expiatory, the second a thanksgiving for the cessation of the pestilence (see on 1-Chronicles 21:26).
After acquiring the threshing-floor by purchase, David built an altar to the Lord there, and offered burnt-offerings and supplicatory-offerings (shelamim: as in Judges 20:26; Judges 21:4; 1-Samuel 13:9) upon it to the Lord. "So Jehovah was entreated, and the plague was turned away from Israel."
This remark brings to a close not only the account of this particular occurrence, but also the book itself; whereas in the Chronicles it is still further stated that Jehovah answered David with fire from heaven, which fell upon the burnt-offering; and that after his prayer had been answered thus, David not only continued to offer sacrifice upon the floor of Aravnah, but also fixed upon it as the site for the temple which was afterwards to be built (1-Chronicles 21:27; 1-Chronicles 22:1); and to this there is appended, in 2-Samuel 22:2., an account of the preparations which David made for the building of the temple. It is not affirmed in the Chronicles, however, that David fixed upon this place as the site for the future temple in consequence of a revelation from God, but simply that he did this, because he saw that the Lord had answered him there, and because he could not go to Gibeon, where the tabernacle was standing, to seek the Lord there, on account of the sword of the angel, i.e., on account of the pestilence. The command of God build an altar upon the threshing-floor of Aravnah, and offer expiatory sacrifices upon it, when connected with His answering his prayer by turning away the plague, could not fail to be taken as a distinct intimation to David, that the site of this altar was the place where the Lord would henceforth make known His gracious presence to His people; and this hint was quite sufficient to determine the site for the temple which his son Solomon was to build.
