Tafsiran Ulangan 22:12: Rashi, Chizkuni, Ibn Ezra & Rashbam

גדלים תעשה לך THOU SHALT MAKE THEE TASSELS [UPON THE FOUR CORNERS OF THY VESTURE] — be they even from a mixture of wool and linen; for this reason Scripture puts them (the prohibition of שעטנז and the command of צצית) in juxtaposition (Yevamot 4a).

גדילים, “twisted strings;” the expression is a variant for קליעה, “plaited work.” This law appears here as in connection with the tzitzit, fringes used in a ritual context that must be attached to four cornered garments, the prohibition for plaiting wool and linen has been waived. (Ibn Ezra)

you must make for yourself tassels The Dissenters claim that this is a separate commandment, applicable at night, as the “fringes” [Numbers 15: 38] are applicable during the day, and for this reason Scripture says which you cover yourself. The Exegetes, though, have transmitted to us the knowledge that this verse discusses the same commandment as the “fringes”, and that it is applicable only during the day. The word tassels is to be interpreted in the sense wherein it was used apropos the building of the Temple: “wreathes of chain-work” [I Kings 7: 17]. The Dissenters derived it from “largeness”; but we shall believe only in the words of our forebears. Scripture mentions this verse in order to specify that the commandment applies only to things with four corners. It is connected to the topic of wool-and-linen, because wool-and-linen is permissible on one’s fringes [Yevamot 4b].
