Numbers 15:38-39 ▼

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

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