Numbers 15:37-40

³⁷And the Lord spake to Mosheh, saying:

³⁸Speak with the children of Israel, and bid them that they make them fringes upon the borders of their garments throughout their generations, and that upon the fringes on the borders they put a ribbon of hyacinth.

³⁹And they shall be to you for fringes, that you may look upon it, and remember all the commandments of the Lord, and do them, and not wander after the imagination of your heart, or after the sight of your eyes, after which you have gone astray.

⁴⁰That you may remember and do all My precepts, and be saints before your God.
