Numbers 15:37-40

³⁷And the Lord spoke to Moses, saying,

³⁸Speak to the children of Israel, and you shall tell them; and let them make for themselves fringes upon the borders of their garments throughout their generations: and you° shall put upon the fringes of the borders a lace of blue.

³⁹And it shall be on your fringes, and you° shall look on them, and you° shall remember all the commands of the Lord, and do them: and you° shall not turn back after your imaginations, and after the sight of your eyes in the things after which you° go a whoring;

⁴⁰that you° may remember and perform all my commands, and you° shall be holy to your God.
