Numbers 15:37-40

³⁷And the Lord said unto Moses, as followeth,

³⁸Speak unto the children of Israel, and say to them, that they shall make themselves fringes on the corners of their garments throughout their generations, and that they shall put upon the fringe of the corner a thread of blue:

³⁹And 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 the inclination of your own heart and the delight of your eyes, in pursuit of which ye have been led astray.

⁴⁰In order that ye may remember, and do all my commandments, and be holy unto your God.
