The title of the second book is _Exodus_. For it was necessary for that which is born to travel through the Red Sea, and pass towards the Desert--by Red the blood is meant, he says--and taste the bitter water. For the "bitter," he says, is the water beyond the Red Sea, inasmuch as it is the path of knowledge of painful and bitter things which we travel along in life. But when it is changed by Moses, that is to say by the Word, that bitter (water) becomes sweet. And that this is so, all may hear publicly by repeating after the poets: "In root it was black, but like milk was the flower. Moly the Gods call it. For mortals to dig it up is difficult; but Gods can do all things."[27] 16. Sufficient, he says, is what is said by the Gentiles for a knowledge of the whole matter, for those who have ears for hearing. For he who tasted this fruit, he says, was not only not changed into a beast by Circe, but using the virtue of the fruit, reshaped those who had been already changed into beasts, into their former proper shape, and re-struck and recalled their type. For the true man and one beloved by that sorceress is discovered by this milk-white divine fruit, he says. In like manner _Leviticus_, the third book, is smelling or respiration. For the whole of that book treats of sacrifices and offerings. And wherever there is a sacrifice, there arises the smell of the scent from the sacrifice owing to the incense, concerning which sweet smell the sense of smell is the test. _Numbers_, the fourth book, signifies taste, wherein speech (or the Word) energizes. And it is so called through uttering all things in numerical order. _Deuteronomy_, again, he says, is so entitled in reference to the sense of touch of the child which is formed. For just as the touch by contact synthesizes and confirms the sensations of the other senses, proving objects to be either hard, warm, or adhesive, so also the fifth book of the Law is the synthesis of the four books which precede it. All ingenerables, therefore, he says, are in us in potentiality but not in actuality, like the science of grammar or geometry. And if they meet with befitting utterance[28] and instruction, and the "bitter" is turned into the "sweet"--that is to say, spears into reaping hooks and swords into ploughshares[29]--the Fire will not have born to it husks and stocks, but perfect fruit, perfected in its imaging, as I said above, equal and similar to the ingenerable and Boundless Power. "For now," says he, "the axe is nigh to the roots of the tree: every tree," he says, "that bringeth not forth good fruit, is cut down and cast into the fire."[30]
