Numbers 15:38-39

38“Speak to the sons of Israel and tell them that they shall make for themselves 1tassels on the corners of their garments throughout their generations, and that they shall put on the tassel of each corner a 2violet thread.

39It shall be a tassel for you 3to look at and 4remember all the commandments of the Lord, so that you will do them and not 5follow your own heart and your own eyes, 6which led you to prostitute yourselves,
