NUM173 Place tzitsis on a four-cornered garment. Key concepts: So that at all times, we remember Hashem's mitzvos. When a King wants his subjects to remember Him, the best thing he can do is place his emblem on their clothing, for they wear clothing all the time and the emblem catches their eye. Our Sages teach that the word tzitsis alludes to the 613 mitzvos of the King of kings, for its numerical equivalent is 600, and on each corner of the garment there are eight strings and five knots (8+5=13), so the total is 613. Also, the mitzvah reminds us that each person belongs to Hashem, body and soul. The white of the tzitsis alludes to man's body, which Hashem created out of earth that He fashioned from snow that is beneath His Throne of Glory. The threads allude to a person's body, which after conception is like strings. The techeiles (bluish) thread of the tzitsis alludes to the soul, which comes from the upper realms of the blue skies. As our Sages teach, “The techeiles is like the sea, and the sea is like the sky, and the sky is like the Throne of Glory.” Although one is a obligated in the mitzvah of tzitsis only if he actually wears a garment that has four corners [or more], still, our Sages warned us repeatedly that one should make every effort to obtain and wear such a garment in order to fulfill the mitzvah. Our Sages teach that he who is careful about the mitzvah of tzitsis will have many servants to attend to his needs. Also, he was careful about tzitzis, to tefillin and mezuzah is assured that he will not sin.
