At that time when David saw that the Lord had answered him in the threshing floor Of Ornan the Jebusite,.... The same with Araunah, 2-Samuel 24:16, with some small variation of the letters, and are of the same signification; both signifying the "ornus", as Hillerus (m) observes, the pine tree or ash; see Isaiah 44:14, in whose threshingfloor David now was, and where he had been praying and sacrificing; and God had accepted his prayer, as the Targum, and had answered him, by causing fire to come down on the sacrifice and consume it, and by ordering the angel to put up his sword in its sheath:
then he sacrificed there; again by the priests, and continued to do so, for he had sacrificed there before, 1-Chronicles 21:26 and finding his sacrifices in that place were acceptable, he repeated them, and did not go to Gibeon, as follows.

when David saw that the Lord had answered him . . ., he sacrificed there--or, "he continued to sacrifice there." Perceiving his sacrifice was acceptable, he proceeded to make additional offerings there, and seek favor by prayer and expiatory rites; for the dread of the menacing angel destroying Jerusalem while he was absent in the center of worship at Gibeon, especially reverence for the Divine Being, led him to continue his adorations in that place which God (2-Chronicles 3:1) had hallowed by the tokens of His presence and gracious acceptance.
Sacrificed - When he perceived that his sacrifice was acceptable to God, he proceeded to offer more sacrifices in that place.
