Translation:Shulchan Aruch/Orach Chaim/17
17: Who is Required to Wear Tzitzit.
1 Even though it says "and you shall see it", a blind person must wear tzitzit because he was added from "wherewith you cover yourself". And the verse of "and you shall see it" is needed to reduce a night-garment (see below, Chapter 18).
2
Women and slaves are exempt because it is a time-dependent commandment.
Gloss: And nevertheless, if they wish to wrap in it and to say the blessing on it, it is up to them to do so as with all time-dependent commandments [Tosafot and the Rosh and the Ran, Chapter 2 of Rosh Hashanah and First Chapter of Kiddushin]. However, it looks as if they are more observant than others, therefore, they should not wear tzitzit, as it is not a commandment of the person [Agur Section 27]. [This means he does not have to buy himself a tallit in order that he be required to wear tzitzit. And below in Chapter 19 it says when he has a shawl with four corners and wears it.]
A tumtum and an androgynous are required because of doubt and they should wrap without a blessing.
[Explanation: a tumtum is not known whether he is male or female, and an androgynous has male and female genitals.]
[Gloss: And according to the custom of women to say the blessing when they fulfill time-dependent commandments, they too should say the blessing.] [His own words].
3
A child who knows how to wrap, his father must buy him tzitzit to educate him.
Gloss: And in particular if he knows to put two tzitzit in front of himself and two in the back of himself [Notes of Maimuni Chapter 3] and knows to hold the tzitzit in his hand during the reading of the Shema [Mordechai, end of Chapter Lulav Hagazul].
