(Fol. 43b) We are taught in a Baraitha concerning the passage (Num. 15, 39) That ye may look upon it, i.e., look upon this commandment and ye will remind yourselves about another comandment which depends on it. This is the reading of the Sh'ma; for we are taught in a Mishna: From what time may one read the Sh'ma of the morning [prayer]? From the time one can distinguish [before the daylight] between blue and white colors. We are taught in another Baraitha: That ye may look upon them, and remember all the commandments of the Lord, i.e., look upon this commandment and ye will remind yourselves of another commandment which is mentioned close to it. To what does it refer? To the following passage (Deut. 22, 11) Thou shalt not wear a mingled stuff, wool and linen together. Thou shalt make the fringes. We are taught in another Baraitha: That ye may look upon them, and remember all the commandments of the Lord, i.e., the commandment of the fringes is equal in value to all other commandments. Again we are taught in another Baraitha: That ye may look upon it, and remember all the commandments of the Lord, and do them; i.e., the looking upon it causes one to remind himself [of his duties]; the reminding [of a thing] brings one to the action of it. R. Simon b. Jochai says: "Whoever is careful in observing the commandments of the fringes will be rewarded to greet the presence of Shechina; for it is written here that ye may look upon it (Ur-ithem), and again it is written (Deut. 6, 13) The Lord thy God Shalt thou fear (Tira); and Him shalt thou serve."
