And according to this, that which the Rambam wrote in chapter 20: The sages commanded that a person give a small amount of his property to his daughter so that she may marry with it, and this is what is called parnasah; one who marries off his daughter without specification shall not provide her with less than the clothing that is adjudicated for the wife of a poor man in Israel, as I have written [in chapter 13]; in what case does this apply? When the father was poor, but if he was wealthy, it is fitting for him to give to her according to his wealth. Thus far his words. And it appears explicitly that the law he wrote to give a small amount of his property so that she may marry with it is the law we brought in section 1, and why did he not write a tenth of the property? Because we hold that it is not precisely so, as will be explained in siman 113, that orphans who marry off their sisters from their inheritance, we estimate how much the father would have given them, and if we do not know his estimation, we give her a tenth of the property; therefore he wrote generally that he should give a small amount of his property according to his will. And the second law that he wrote, that he shall not provide her with less than the clothing that is adjudicated for the wife of a poor man in Israel, this is the Mishnah we brought in section 2, and he also explains that this refers to garments alone. And why did he not write fifty zuz? Because he follows his reasoning in chapter 13 that this sum depends on the place and the time.
ולפ"ז, זה שכתב הרמב"ם בפ"כ: צוו חכמים שיתן אדם מנכסיו מעט לבתו כדי שתנשא בו וזה הוא הנקרא פרנסה, המשיא את בתו סתם לא יפחות לה מכסות שפוסקין לאשת עני שבישראל כמ"ש [בפי"ג], בד"א כשהיה האב עני אבל אם היה עשיר ה"ז ראוי ליתן לה כפי עשרו עכ"ל, ונראה להדיא שהדין שכתב ליתן מנכסיו מעט כדי שתנשא בו זהו הדין שהבאנו בסעי' א', ולמה לא כתב עישור נכסים? משום דאנן קיי"ל דלאו דווקא הוא כמו שיתבאר בסי' קי"ג דיתומים המשיאים אחיותיהם מירושתם שמין כמה האב היה נותן להם ואם לא ידענו אומדנתו נותנין לה עישור נכסים, ולכן כתב סתם שיתן מעט מנכסיו כפי רצונו, והדין השני שכתב לא יפחות לה מכסות שפוסקין לאשת עני שבישראל זהו המשנה שהבאנו בסעי' ב', ומפרש ג"כ דזהו על בגדים בלבד, ולמה לא כתב חמישים זוז? משום דהולך לשיטתו בפי"ג דסכום זה תלוי לפי המקום והזמן.
