Today as I was thinking of the sacramental prayers, a couple parallels jumped out to me. Specifically I was comparing them to a passage in Numbers Chapter 15 (which is the 3rd part of 'the Shema'), which details the rationale for observant jews to wear tassels on their clothing: Numbers 15:37-41: "And the LORD spake unto Moses, saying, Speak unto the children of Israel, and bid them that they make them fringes in the borders of their garments throughout their generations, and that they put upon the fringe of the borders a ribband of blue: And it shall be unto you for a fringe, that ye may look upon it, and remember all the commandments of the LORD, and do them; and that ye seek not after your own heart and your own eyes, after which ye use to go a whoring: That ye may remember, and do all my commandments, and be holy unto your God. I am the LORD your God, which brought you out of the land of Egypt, to be your God: I am the LORD your God." This passage outlines the steps for why a physical token is important for them. To paraphrase: "a fringe, that ye may 1) look upon it, 2) and remember all the commandments of the LORD, 3) and do them [...] 2) That ye may remember, 3) and do all my commandments, 4) and be holy unto your God" Or more briefly: Look (at the fringe) -> Remember the commandments -> Do the commandments -> Be holy. As I listened to the sacramental prayers today, I couldn't help but see them as being parallel to the passage in numbers: Numbers 15: make them fringes in the borders of their garments throughout their generations, and that they put upon the fringe of the borders a ribband of blue: v39 And it shall be unto you for a fringe, ⮣ (1) that ye may look upon it, and ⮣ (2) remember all the commandments of the LORD, [Ex 20 v7: “Thou shalt not take the name of the LORD thy God in vain.”] [Ex 20 v7, reworded: I know this is a stretch): “Thou shalt take the name of the LORD thy God, not in vain.”] ⮣ (3) and do them; […] That ye may ⮡ (2) [that ye may] remember, and ⮡ (3) [that ye may] do all my commandments, and ⮣ (4) [that ye may] be holy unto your God. Moroni Chapter 4: ⮡ (1) that they may eat ⮡ (2) in remembrance of the body of thy Son, and ⮡ (3) witness unto thee, O God, the Eternal Father, that they are willing to take upon them the name of thy Son, ⮡ (2) and [to] always remember him, ⮡ (3) and [to] keep his commandments which he hath given them, ⮡ (4) that they may always have his Spirit to be with them Moroni Chapter 5: ⮡ (1) that they may do it [i.e. drink] ⮡ (2) in remembrance of the blood of thy Son, which was shed for them; 
 ⮡ (2) that they may witness unto thee, O God, the Eternal Father, that they do always remember him, ⮡ (4) that they may have his Spirit to be with them. I have had a feeling that there was a connection there for a while, but this was the first time it came to me with this much clarity. I don't know of any explicit statement in scriptures that wearing tassels is no longer needed, but given the parallels it seems that the sacrament in some ways serves the same function as the tassels once did for the Israelites?
