Such chapters will serve as an introduction to others; they will contain some reference to the signification of a homonym which I do not wish to mention in that place, or explain some figure; point out that a certain expression is a figure; treat of difficult passages generally misunderstood in consequence of the homonymy they include, or because the simile they contain is taken in place of that which it represents, and vice versâ. Having spoken of similes, I proceed to make the following remark:—The key to the understanding and to the full comprehension of all that the Prophets have said is found in the knowledge of the figures, their general ideas, and the meaning of each word they contain. You know the verse:— “I have also spoken in similes by the Prophets” (Hosea xii. 10); and also the verse, “Put forth a riddle and speak a parable” (Ezek. xvii. 2). And because the Prophets continually employ figures, Ezekiel said, “Does He not speak parables?” (xxi. 5). Again, Solomon begins his book of Proverbs with the words, “To understand a proverb and figurative speech, the words of the wise and their dark sayings” (Prov. i. 6); and we read in Midrash, (Shir ha-shirim Rabba, i. 1); “To what were the words of the Law to be compared before the time of Solomon? To a well the waters of which are at a great depth, and though cool and fresh, yet no man could drink of them. A clever man joined cord with cord, and rope with rope, and drew up and drank. So Solomon went from figure to figure, and from subject to subject, till he obtained the true sense of the Law.” So far go the words of our Sages. I do not believe that any intelligent man thinks that “the words of the Law” mentioned here as requiring the application of figures in order to be understood, can refer to the rules for building tabernacles, for preparing the lulab, or for the four kinds of trustees. What is really meant is the apprehension of profound and difficult subjects, concerning which our Sages said, “If a man loses in his house a sela, or a pearl, he can find it by lighting a taper worth only one issar. Thus the parables in themselves are of no great value, but through them the words of the holy Law are rendered intelligible.” These likewise are the words of our Sages; consider well their statement, that the deeper sense of the words of the holy Law are pearls, and the literal acceptation of a figure is of no value in itself. They compare the hidden meaning included in the literal sense of the simile to a pearl lost in a dark room, which is full of furniture. It is certain that the pearl is in the room, but the man can neither see it nor know where it lies. It is just as if the pearl were no longer in his possession, for, as has been stated, it affords him no benefit whatever until he kindles a light. The same is the case with the comprehension of that which the simile represents. The wise king said, “A word fitly spoken is like apples of gold in vessels of silver” (Prov. xxv. 11).
