"But Sarah the wife of Abraham had not borne him any child. And she had an Egyptian handmaiden, whose name was Hagar. And Sarah said unto Abraham, Behold, the Lord


 
has closed me up, so that I should not bear children; go in unto my handmaiden that thou mayest have children by her." Genesis xvi. 1. The name Sarah, being interpreted, means "my princedom." And the wisdom which is in me, and the temperance which is in me, and the particular justice, and each of the other virtues which belong to me alone, are the princedom of me alone. For such virtue, being a queen from its birth, rules over and governs me who have determined on obeying it.
 Now this virtue, Moses (making a most paradoxical assertion) reports, as being both barren and also most prolific, since he affirms that the most populous of all nations is sprung from it. For, in real truth, virtue is barren with respect to all things which are evil, but is so exceedingly prolific of good things, that it stands in no need of the art of the midwife, for it anticipates it by bringing forth before its arrival. Therefore animals and plants, after considerable intervals and interruptions, bring forth their appropriate fruits, once, or at most twice a year; according to the number of times which nature has appointed each of them, and which is properly adapted to the seasons of the year. But virtue without any interruption, without any interval or any cessation, is continually bringing forth at all times and on all occasions, not indeed children, but virtuous reasonings, and irreproachable counsels, and praiseworthy actions.
 But neither is wealth, which it is not possible to employ, of any advantage to its possessors, nor is the fertility of wisdom of any service to us, unless it also brings forth such things as are serviceable to us. For some persons it judges to be in every respect worthy of living in its company; but others appear to have not yet arrived at such an age, as to be able to support so highly praised and well regulated a charge; whom, however, it permits to enter upon the preliminaries of marriage, holding out to them a hope that they may hereafter consummate the wedlock.
