For since our soul is composed of two parts, and since the one contains the rational faculties, and the other the irrational ones, it follows that each part must have its own peculiar virtue, Leah being the virtue of the rational part, and Rachel of the irrational.
Section 27
For the one trains us, by means of the external senses and the parts of speech, to look contemptuously upon all things which it is proper to disregard, such as glory, and wealth, and pleasure, which the principal and general multitude of common men look upon as things to be admired and striven for, their sense of hearing being corrupted, and the tribunal of all the other external senses being corrupted likewise.
Section 28
But the other teaches us to turn away from that uneven and rough road which is never approached by souls that love virtue, and to go smoothly along the smooth road without any stumbling and without meeting any hindrances in the path.
Section 29
Therefore the handmaiden of the former of the two citizen wives will necessarily be the power of interpretation as exercised by means of the organs of speech, and also the rational invention of sophisms, deceiving man by a well-imagined plausibility; and its necessary nourishment is meat and drink.
Section 30
The historian has recorded for us the names of the two handmaidens, calling them Zilpah and Billah. Genesis xxx. 1. The name Zilpah, being interpreted, means "a mouth going forth," a symbol of that nature which interprets and speaks. But Billah means "a swallowing," which is the first and most necessary support of all mortal animals. For it is by swallowing that our bodies are established firmly, and the cables of life are attached to this action as to a sure foundation.
Section 31
Accordingly the practiser of virtue lives with all the aforesaid powers, with some as with free women and citizens, and with others as slaves and concubines. For he is enamoured of the motion of Leah; and a smooth (λεία) motion existing in a body would Genesis xxx. 1. be calculated to produce health, and, when existing in a soul, it would produce virtue and justice. But he loves Rachel, wrestling with his passions, and preparing himself for a struggle of temperance, arraying himself in opposition to all the objects of the external senses.
Section 32
For there are two kinds of advantage, either that according to which we enjoy blessings, as in peace, or else that which comes from arraying one’s self in opposition to and from removing evils as in war. Now Leah is the wife according to whom it happens to the husband to enjoy the elder, and more important, and dominant blessings; and Rachel the wife, according to whom he obtains what resemble the sports of war. Such then is his way, if left with his citizen wives.
Section 33
But the practiser of virtue also wants Billah, that is, swallowing, but as a slave and a concubine; for without food and vitality, living well could not possibly be the lot of the man, since things indifferent are always the foundation of what is better; and he also wants Zilpah, that is to say, interpretation by means of utterance, in order that the rational part itself may, in a twofold manner, contribute to perfection, both from the fountain existing in the intellect, and also from the stream flowing therefrom in the organ of the voice.
Section 34
But these men were husbands of many wives and concubines, not only of such as were citizens, as the sacred scriptures tell us. But Isaac had neither many wives nor any concubine at all, but only his first and wedded wife, who lived with him all his life.
Section 35
Why was this? Because the virtue acquired by teaching, which Abraham pursues, requires many things, both such as are legitimate according to prudence, and such also as are illegitimate according to the exegetical contemplations of preliminary instruction. And there is also a virtue which is made perfect by practise, to which Jacob appears to have been devoted; for exercises consist of many and various dogmas and doctrines, some leading and others following, some leading the way, and others arriving later, and bringing at one time more serious, and at other times lighter labours.
Section 36
But the self-instructed race, of which Isaac was a partaker, the excellent country of the mastery over the passions, has received as its share a nature simple, and unmixed, and unalloyed, standing in no need of either practise or instruction in which there is need of the concubine sciences, and not only of the citizen wives; for when God has showered down from above that most requisite benefit of knowledge, self-taught, and having no need of a preceptor, it would be impossible any longer for a man to live with the slavish and concubine arts, having a desire for bastard doctrines as his children. For the man who has arrived at this honour, is inscribed as the husband of the mistress and princess virtue; and she is called in the Greek language, perseverance, but among the Hebrews her name is Rebekkah.
Section 37
For he who, by reason of the happy constitution of his own nature and by the prolific fertility of his soul, has attained to wisdom without encountering labour or enduring hardship, stands in need of no further improvement;
Section 38
for he has at hand the perfect gifts of God, inspired by means of those most ancient graces, and he wishes and prays that they may remain lasting. In reference to which, it appears to me to be that the Author of all goodness gave him perseverance as his wife, in order that his mercies might endure for ever to the man who had her for his wife.
