put fire] The fire that kindled the sacrifice at first, came down from heaven, Leviticus 9:24. that fire once kindled, was to be continually nourished with fire, that it might never goe out: any fire but that was accounted strange fire: and to bring strange fire, to burne either sacrifice or incense, was impious, and perillous; as the example of Nadab and Abihu sheweth. This putting of fire then upon the Altar, was either a continuance of fire by putting more fewell unto it, and laying the wood in order upon it; or it was the laying of the fire on the Altar againe, when it had been removed, for the taking away the ashs, (when it was too full of them) that it might be cleansed: and this fire was not onely instrumentall to burne the legall sacrifice; but typicall to signifie the zeale of the Evangelicall Sacrifice, Jesus Christ; whose zeale for his Fathers glory, did eate him up, John 2:17. and gave him up for his brethrens safetie, to death, upon the Altar of the Crosse, which is as violent and painfull death, as by burning with fire.
