Numbers 15:38-41

38Speak to the children of Israel, and bid them that they make them fringes on the borders of their garments throughout their generations, and that they put upon the fringe of the borders a cord of blue: 39And it shall be to 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 your own heart and your own eyes, after which ye use to go astray: 40That ye may remember, and do all my commandments, and be holy to your God. 41I am the LORD your God, who brought you out of the land of Egypt, to be your God: I am the LORD your God.
