phylacteries: Pious Jews sometimes wore small prayer boxes, called phylacteries. These were placed on the head and the upper left arm. Inside were written copies of important Old Testament commands (see Deuteronomy 6:6–9; 11:18–19).
Another custom was wearing tassels, which were also a sign of devotion (see Matthew 9:20; see also Numbers 15:38–41). Some made their tassels extra long to draw attention to their religious devotion.
