And concerning this doctrine Moses also records a law, which he makes with great beauty and suitableness. And it runs thus, "If a man have two wives, the one of them beloved and the other hated; and if both the one who is beloved and the one who is hated have borne him children, and if the child of her who is hated is the first-born, then it shall be in the day in which he divides the inheritance of his possessions among his sons that he shall not be able to give the inheritance of the first-born to the son of the wife that is beloved, overlooking his first-born son, the son of her who is hated; but he shall recognise the son of her who is hated as his first-born, to give him a double share of all the property that he has acquired; because he is the beginning of his children, and the right of the first-born is his." Deuteronomy xxi. 15.

Consider, O my soul, and know who it is who is hated, and who is the son of her who is hated, and immediately you shall perceive that the chief rights and chief honours belong to no one else but to him alone; for there are two wives cohabiting with each individual of us, hostile and inimical to one another, filling the abode of the soul with the contentions which arise from jealousy. Of these we love one, which is gentle and tractable, and which we think very affectionate and akin to ourselves, and its name is pleasure; but the other we hate, looking upon it as untameable, ungentle, fierce, and very hostile to us, and the name of this one is virtue. Now what mortal is ignorant of the great mysteries of that exceedingly beautiful and greatly contended for pleasure? And who could worthily Genesis xxv. 33. Deuteronomy xxi. 15. describe the multitude or the greatness of the good things which are treasured up by virtue? GRC: following passage was moved by Cohn here.

For two women live with each individual among us, both unfriendly and hostile to one another, filling the whole abode of the soul with envy, and jealousy, and contention; of these we love the one looking upon her as being mild and tractable, and very dear to and very closely connected with ourselves, and she is called pleasure; but the other we detest, deeming her unmanageable, savage, fierce, and most completely hostile, and her name is virtue. Accordingly, the one comes to us luxuriously dressed in the guise of a harlot and prostitute, with mincing steps, rolling her eyes about with excessive licentiousness and desire, by which baits she entraps the souls of the young, looking about with a mixture of boldness and impudence, holding up her head, and raising herself above her natural height, fawning and giggling, having the hair of her head dressed with most superfluous elaborateness, having her eyes pencilled, her eyebrows covered over, using incessant warm baths, painted with a fictitious colour, exquisitely dressed with costly garments, richly embroidered, adorned with armlets, and bracelets, and necklaces, and all other ornaments which can be made of gold, and precious stones, and all kinds of female decorations; loosely girdled, breathing of most fragrant perfumes, thinking the whole market her home; a marvel to be seen in the public roads, out of the scarcity of any genuine beauty, pursuing a bastard elegance.
