Tzitziyot

The people of YHWH are promised health in obedience to the Commandments:  Exodus 15:26
And said, If thou wilt diligently hearken to the voice of YHWH thy G-d, and wilt do that which is right in His sight, and wilt give ear to His commandments, and keep all His statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am YHWH Raphah, [your Healer.]
This was right after the children of Israel left Egypt and before Moses was given the Torah at Mt. Sinai.  It is an everlasting promise for our earthly bodies.

Numbers 15:37-40

And YHWH 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 YHWH, 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 G-d.   Please stay with me for a minute as we watch the amazing way this woman was able to be healed by reaching out to Y'hshuwah while being Torah observant.  The border of the garment in the Hebrew translated to the hem of the garment in the Greek.  This woman knew Torah.  She knew the importance of keeping the Commandments and statutes for health in this life. Matthew 9:20-22 And, behold, a woman, which was diseased with an issue of blood twelve years, came behind him, and touched the hem of his garment: For she said within herself, If I may but touch his garment, I shall be whole. But Y'hshuwah turned him about, and when he saw her, he said, Daughter, be of good comfort; thy faith hath made thee whole. And the woman was made whole from that hour.

 This woman with the issue of blood took the hem of Y'hshuwah's garment, never breaking Torah, nor was Messiah unclean for even a moment!  The statutes in Leviticus 15:19-25 were very strict regarding all the things that were not to be touched to remain clean.  Messiah never touched her in her state of uncleanness, and touching the hem of his garment was not disobedience to Torah.  The hem, or border [fringe] of the garment was not something sat upon or laid upon . . .

Leviticus 15:19, 25

And if a woman have an issue, and her issue in her flesh be blood, she shall be put apart seven days: and whosoever toucheth her shall be unclean until the even . . . And if a woman have an issue of her blood many days out of the time of her separation, or if it run beyond the time of her separation; all the days of the issue of her uncleanness shall be as the days of her separation: she shall be unclean.

Zach's great video about tzitziyot and the Scriptural account of this particular situation, I find to be so amazing and inspiring in my own life as a follower of Y'hshuwah and also a servant/child of YHWH.  Not only is wearing tzitziyot, walking in obedience, it is also walking in readiness of service to bring glory to YHWH.
