Numbers 15:38-40 MSG

38 "Speak to the People of Israel. Tell them that from now on they are to make tassels on the corners of their garments and to mark each corner tassel with a blue thread.
39 When you look at these tassels you'll remember and keep all the commandments of God, and not get distracted by everything you feel or see that seduces you into infidelities.
40 The tassels will signal remembrance and observance of all my commandments, to live a holy life to God.
