Numbers 15:38-41

38“Speak to the Israelites and tell them that throughout the generations to come they are to make for themselves tassels for the corners of their garments, with a blue cord on each tassel. 39These will serve as tassels for you to look at, so that you may remember all the commandments of the LORD, that you may obey them and not prostitute yourselves by following your own heart and your own eyes.

40Then you will remember and obey all My commandments, and you will 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.”
