Leviticus 9:24 - Wesley's Explanatory Notes

And there came a fire — In token of God's approbation of the priesthood now instituted, and the sacrifices offered, and consequently of others of the like nature. And this fire now given was to be carefully kept, and not suffered to go out, Leviticus 6:13, and therefore was carried in a peculiar vessel in their journeys in the wilderness. From before the Lord — Or, from the presence of the Lord, that is, from the place where God was in a special manner present, either from heaven or from the holy of holies. They shouted — As wondering at, rejoicing in, and blessing God for this gracious discovery of himself, and his favour. This also was a figure of good things to come. Thus the Spirit descended in fire upon the apostles, so ratifying their commission, as this does that of the priests. And the descent of this holy fire into our souls, to kindle in them devout affections, and such an holy zeal as burns up all unholiness, is a certain token of God's gracious acceptance.
