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).
