Yet these two fires may be compared, namely the strange fire to Leaven, to the Sea water which is salt, and to Vinegar, a corrupted Wine, and other sorts of Leavens Fires against nature. And the Celestiall to the Altar to pure and unleavened Past, to sweet water fit to drinke, to _Aqua vitæ_, without Vinegar, representing the state of innocence in our first fathers, before their transgression, and the simplicitie of their knowledge, infused into them by the Creator. But when they were once tempted afterwards with ambition, to know more then they should, they would by humane discourse become more subtill and sage, in tasting the fruit of knowledge of good and evill; their Past without Leaven began to swell, to bee proud with the Leaven themselves introduced, which perverted and spoyled it, appropriating it to corporall and sensible things, for the bread which wee eate is leavened, but that which wee use in the Church must not be so, and not without cause, for unleavened bread will bee kept six moneths without molding or corrupting; that leavened bread will not keep so many weekes. It is therefore that the Apostle said, a little Leaven corrupts the whole Masse: Because that one propriety of the Leaven is to convert into their corruption all that is adjoyning of their nature, as Vinegar doth Wine, and Leaven pure Past, also Rennet which is in the number of Leavens. And when they have no Leaven, they make some, corrupting the Past with Vinegar, Lees of Beere, Egges, and like substances, who by their corruption acquire to themselves the propertie of strange fire which is able to convert into its nature, that where it can bite, as wee may see in a Feaver against naturall heate, so that hee turnes it selfe into all things, and all into it selfe, according to _Heraclitus_, who set it downe for the Principall, yet after _Zoroastres_, who thought all things were begotten of Fire after it was extinguished, for being living it begets nothing, no more doth Salt, nor the Sea which _Homer_ calls ἀτρὺγετος unfruitfull, which doth nothing but consume and destroy: An immense and wicked portion of things (saith _Pliny_) and wherein it is doubtfull whether it consume or bring forth more things. Leaven then is a strange fire, and is indeed caustique or burning, for applyed to naked flesh, it engenders therein little _cloches_, which shewes its fierynesse, (also it doth not so without Salt) called for this reason in Latine _fermentum_, Leaven which increaseth by bring warme: and in Greek ζύμη Leaven from ζέω to boile. The Chymicks call it the interior fire, fire within the vessell, for wee see by experience, that bread, if the Past be not leavened, what boyling soever you give it, shall never be but of a hard and uneasy digestion, greatly oppressing the stomach, if the Leaven which they joyne thereunto make it boyle within; whence then it comes that _Moses_ so knowing a man, and so illustrated with the Divine
