What Does Tzitzit Mean?
The word tzitzit (צִיצִית) is literally defined as “fringes,” and refers to the strings attached to the corners of the tallit, the Jewish prayer shawl. It also refers to the poncho-like mini-tallit that is worn throughout the day, often under a shirt. Here’s how the mini-tallit came to be.
Tzitzit: The Mini-Tallit
G‑d commanded the Jewish people to affix fringes to the corners of their clothing so that they would constantly remember Him and His commandments.1 At that time, the common garment was a simple sheet of cloth, and the mitzvah was to affix fringes to each of its four corners. But styles changed over the centuries, and the simple garments of biblical times were replaced with robes, jackets, trousers and shirts. What would happen to the tallit? Jewish men then began to fulfill the mitzvah in the following two ways:
a) During prayer, we drape ourselves in a tallit gadol (“big tallit”), which has essentially remained the same since ancient times. (Read about the Tallit here.)
b) We wear a little poncho called a tzitizit, tallit katan (“small tallit”), or arba kanfot (“four corners”). For most of us, it fits neatly under a shirt.
Tzitzit: The Tassles
The fringes attached to the tallit of either size are called tzitzit. They are almost always made of white wool, and must be spun with the sacred intention that they be used for the mitzvah. So if you need to replace a snapped thread, make sure that you purchase special tzitzit threads.
The strings must be tied onto the garment, so a ready-made tassle that is sewn or clipped into place is invalid, as would be certain repairs done to an existing tassle that has torn.2
On each corner, four threads are threaded through a hole and looped over, so that there are eight strings hanging down. A series of double knots and coils then join the first few inches of each corner’s tassel into a single cord. The remainder of the eight threads are then free to hang down.
What the Tzitzit Mean
The eight strings and five knots are a physical representation of the Torah's 613 mitzvahs. It works like this: Each letter in the Hebrew alphabet has a corresponding numerical value (gematria). The numerical values of the five letters that comprise the Hebrew word tzitzit add up to 600. Add the eight strings and five knots of each tassel, and the total is 613.


I have a different take on this, the Tzitzit must be blue. The fringe on the border, is of course symbolic of you. Moses could have said that the fringe must be white, or pure, clean, and holy or even red with great courage to punish evildoers, but no blue means something different here. A man was found gathering sticks and G-d said to put him to death, why? Obviously he violated the Sabbath laws but in what way? Was it merely the physical act? I don't think so. I think the greater crime lies in the meaning of the root words, the man was mentally gathering his thoughts in a hard and closed off way, like someone closing the door and refusing to let Hashem in their own home. So we must be open and welcoming, as the fringe of the border of infinite chesed, loving kindness without end. Our hearts must be filled with love and kindness, fully open and prepared, like Abraham ready to receive any guests. The tzitzit is blue like the blue star of Isreal shining brilliantly in the darkness.
Thank you for your insight....
nowhere does scripture state that "the Tzitzit must be blue" but rather have one blue thread.
Numbers 15:38
“Speak to the Israelites and tell them that throughout the generations to come they are to make for themselves tassels for the corners of their garments, with a blue cord on each tassel.
